Abstract

The utility model relates to a total dissolved solids (TDS) test pen, which comprises a signal acquisition module. The signal acquisition module comprises a detection electrode. The test pen also comprises a signal amplification module, a signal calculation module and a signal display module, wherein the signal acquisition module, the signal amplification module, the signal calculation module and the signal display module are sequentially connected, and are also connected with a power supply. By the TDS test pen, the content of dissoluble solids in water can be conveniently and quickly tested. In addition, water temperature can be measured, and is used for temperature compensation to ensure the accuracy of a TDS value. The TDS value is displayed on a pen body through a liquid crystal display, and by the TDS value, water quality can be intuitively judged. The TDS test pen is a portable instrument for daily water quality monitoring.

Description

The TDS test pen

Technical field

The utility model relates to a kind of test pen, the TDS test pen of total dissolved solid value in particularly a kind of test water.

Background technology

TDS is the abbreviation of English Total Dissolved Solids, is meant the total content of the solid matter that is dissolved in the water, and comprises salt, metallic ion, mineral matter etc.Unit is ppm or mg/L.It shows to be dissolved with what milligram total dissolved solids in 1 premium on currency, in other words the total ion concentration in 1 premium on currency.The TDS value has been represented dissolved matter impurity content in the water, and the TDS value is big more, explain that the impurity content in the water is big, otherwise impurity content is little.The numerical value of TDS is mainly used in the clearance effect of inspection water filter, promptly judges the clean-up performance of potable water with the numerical value of TDS, also can be widely used in the measurement chemical industry, and the Shui nationality are cultured the plot degree of domestic water etc.

At present, the family expenses water cleaning systems has been come into huge numbers of families, therefore, more needs a kind of conveniently water quality detection equipment, in order to monitoring water quality quality, confirms the opportunity that core component such as filter core in the water cleaning systems is changed.

Summary of the invention

The purpose of the utility model is, a kind of convenient dexterous water quality detection equipment is provided, particularly a kind of TDS test pen.

The technical scheme of the utility model is:

A kind of TDS test pen; It includes a signal acquisition module; Said signal acquisition module comprises a test electrode; Said test pen also includes a signal amplification module, a calculated signals module and a signal display module, and said signal acquisition module, signal amplification module, calculated signals module, signal display module connect successively, and said operational module also is connected with power supply;

Further; Said signal amplification module, calculated signals module, signal display module are arranged in the body; Said signal acquisition module is set in place in a probe of body lower end; Said power supply is to place the pen battery in the section detachable battery storehouse on one's body, and said signal display module is one to be arranged on a liquid crystal/light-emitting diode display on one's body;

Further; Said signal acquisition module also is connected with a control panel; Said control panel is provided with on/off button, hold button and temperature button, and said on/off button is controlled the closure and the disconnection in whole loop, the closed and disconnection of said temperature button control displays temperature.

Its principle is that the on/off button in the control module is used to control the folding in whole loop; When it was set to " opening ", the loop was connected, and at this moment the test pen probe was stretched in the tested water body; Test electrode can test out the electrical conductivity signal of current water body, and simultaneous temperature sensor measurement temperature signal compensates the TDS value, and this signal is after signal amplification module, calculated signals module are handled successively; Draw the TDS value of current water body, its unit is PPM, and is presented in the signal display module.When pressing the temperature button, in signal display module, show temperature value measured.

The beneficial effect of the utility model is, uses the TDS dissolved solid test pen of the utility model, can conveniently test water quality; And can carry out auto thermal compensation, to eliminate the measuring error under the tested water body different temperatures, precision is higher; Its test number is presented at by liquid crystal/light-emitting diode display on one's body the pen, and numerical value can judge intuitively that water quality is good and bad thus; Also can measure the duty of water purification system, with decision core component such as renew cartridge whether more.

This product important technological parameters: measurement range: 0-999ppm, the above X10 automatically of 999ppm; Accuracy: ± 2%; Battery: 1.5v*2 (button cell); With lock function, temperature compensation function, automatic closing function; Battery life: sustainable use 1000 hours; Size: 16.0*3.4*2.3cm; Weight: 70g.

Embodiment

Below in conjunction with Fig. 1, Fig. 2, set forth the embodiment of the utility model:

By Fig. 1, shown in Figure 2, the TDS test pen of present embodiment, it includes a body 1; Body lower end is provided with a probe 2, and probe is outer to be with a cap for brush 3, and the upper end of a body has a detachable battery storehouse 4; Be provided with a signal acquisition module in the said probe, this signal acquisition module includes a detecting electrode, and a temperature sensor; Signal acquisition module is connected with signal amplification module on being arranged at a body 1, also is provided with a calculated signals module on the body 1, and the one of which end is connected with the signal amplification module; The other end is connected with a liquid crystal or light-emitting diode display, and said signal acquisition module comprises a temperature compensation processor, and this temperature compensation processor can be according to temperature sensor probe temperature and water body conductivity temperature coefficient; The signal value output of automatic compensating signal computing module, because of the different water body TDS numerical errors that produce of tested water body temperature, said signal acquisition module also is connected with a control panel with automatic compensation; When said control is used; The cap for brush 3 is pulled up, pressed ON/OFF by (ON/OFF) button to " opening " state, show 000PPM on the LCDs this moment; Test pen probe segment 2 is put into water to waterline height, and the LCDs of TDS test pen can demonstrate the TDS value of tested water.Treat numerical value show 10 seconds stable after, press hold button HOLDN, from water, take out test pen, read the TDS value that numerical value above the liquid crystal display is measured liquid.When X10 appearred in demonstration, real data should multiply by 10 times.When pressing hold button once more, test pen recovers the measurement state.When needs show the measurement temperature, press the temperature button, promptly show and measure temperature.After finishing using, close ON/OFF, dry probe water mark, the cap for brush is built.

Panel is provided with on/off button, hold button and temperature button, and said on/off button is controlled the closure and the disconnection in whole loop, the demonstration of said temperature button control temperature.
