Description
Technical field
The utility model belongs to instrument field, refers in particular to be applied to the servicing unit of water assay.
Background technology
The measurement of pH meter is influenced by temperature very greatly relative to the measurement of electrical conductivity, and temperature is the material impact for influenceing pH
Factor.
General pH meter has temperature compensation function, and this easily causes illusion, thinks that TWS change will not be produced
Measurement error, in fact really not so, according to pH measuring principles, the pH for measuring water sample can be represented by the formula：
PH=pHs-（E-Es）×F/(2.3026RT)
The temperature-compensating of instrument is that coefficient F/ (2.3026RT) is compensated, it is impossible to compensate reference electrode with temperature
Change and water sample pH variation with temperature in itself, and pH value of steam pH Con trolling index when being 25 DEG C, when deviateing 25 DEG C pair
The pH value answered changes, and the pH value for hence deviating from 25 DEG C of measurements cannot function as accurate controlling value.
It is that cannot eliminate the error that temperature is caused to water sample pH measurements with the method for temperature-compensating, it is therefore necessary to strict control
The temperature of water sample is in the range of 25 ± 2 DEG C.
Instrument board is delivered to after steam water sampling is once cooled down water sample, be divided into two-way in instrument board supplies online instrument all the way
Table is used, and for manual laboratory sampling, give the water sample of instrument has secondary thermostat to another road water sample, and supplies chemical examination by hand
Water sample does not have constant temperature, and when being detected with portable pH tables, 25 DEG C of temperature departure will produce error, just be needed to eliminate this error
TWS is controlled at 25 DEG C using thermostat.
The content of the invention
The utility model is related to a kind of portable power generation factory water sample measurement thermostat, to solve to be detected with portable pH tables
When 25 DEG C of temperature departure will produce the problem of error.
The utility model takes the technical scheme to be：Detected water sample pipeline connects overflow valve and water sample flow valve, the water respectively
Sample flow valve is connected with spinner flowmeter, and the spinner flowmeter is connected by pipeline with once pre- thermostat water inlet, once
Pre- thermostat delivery port is connected by pipeline with the water inlet of electric refrigerated constant temperature device, the delivery port of the electric refrigerated constant temperature device
It is connected with for manual laboratory sampling pipeline, cooling water pipeline is connected with once pre- thermostat, also with the electric refrigerated constant temperature device
Connection.
The utility model has the advantages that structure is novel, the water by its constant temperature is used for the pH and electrical conductivity of online water sample etc.
Accurate measurement.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
Detected water sample pipeline 1 connects overflow valve 2 and water sample flow valve 3 respectively, and the water sample flow valve connects with spinner flowmeter 4
Connect, the spinner flowmeter 4 is connected by pipeline with the once water inlet of pre- thermostat 5, and once the delivery port of pre- thermostat 5 passes through
Pipeline is connected with the water inlet of secondary electric refrigerated constant temperature device 6, delivery port and the confession craftization of the secondary electric refrigerated constant temperature device 6
Test sampling line 7 to connect, cooling water pipeline 8 is connected with once pre- thermostat, be also connected with the secondary electric refrigerated constant temperature device.
Operation principle, can be arranged in a casing, by detected water sample by water sample flow valve 3, rotor stream with the present apparatus
Gauge 4 enters in once pre- thermostat 5, carries out first time constant temperature, it is therefore an objective to reduce the power of secondary electric refrigerated constant temperature device,
Enter in secondary electric refrigerated constant temperature device from the once detected water sample out of pre- thermostat 5, further keep constant temperature.
