Description
Technical field
The utility model relates to a kind of carbonmonoxide detector, specifically a kind of Portable Detector of Carbon Monoxide.
Background technology
Along with developing rapidly of industry; the place that the mankind contact toxic and harmful gets more and more; cause thus the mankind's harm itself increasing; each intoxication accident; make the to protect mankind inherently safe importance in developing industry of recognizing that people regain consciousness, therefore various harmful gas detecting instruments gradually become industrial safety produce in requisite safeguard.
Gas detecting instrument instrument application field is extensive, covered industry, agricultural, traffic, science and technology, environmental protection, national defence, the each side such as space flight and aviation and daily life, the common common miniaturization of gas detecting instrument instruments and meters, portable, work alone or be unified into network, be widely used in oil, chemical industry, metallurgical, mining, pharmacy, semiconductor machining, industry spot and the families such as spraying packing, market, liquefied gas station, gas station, refuelling stations etc. are civilian, commercialization needs fire-proof and explosion-proof, preventing poisoning, air-polluting place, and Agricultural greenhouse gas detects, biogas is analyzed and biogas security monitoring and environmental protection emergent accident, the attack of terrorism, the aspects such as dangerous material accumulating.
Detect airborne carbon monoxide and have important value.On the one hand, carbon monoxide is scentless, but has height toxicity simultaneously.Therefore for carbon monoxide, present maximum work space concentration is only 30ppm.Now, if at indoor burner or the chimney of existing, at rough burning, while lacking air, in flue gas, carbonomonoxide concentration may be several percent by volume.If smoke pipe blow-by or device chimney exhaust gas be due to disadvantageous pressure dependence, for example, because the chimney adversely extending or operation nearby have smoke exhaust ventilator, and leak into indoorly, can form and cause poisoning carbonomonoxide concentration.This is enough to cause Health cost and even death due to poisoning in worst situation.For example CDC is in " anthracemia: fact sheet provides: have every year 500 people dead due to anthracemia in the U.S..The in the situation that of vexed combustion, also can form a large amount of carbon monoxide.Except the poisoning danger of personnel, therefore this gas be also used as fire indication gas and therefore its detection be also used to find ahead of time fire condition.
At present, carbonmonoxide detector device instrument key circuit possesses two aspect functions, requires under the state of system boot on the one hand, the input block of man-machine interaction is provided, be on the other hand under system closedown power-down conditions, give with system an of short duration powered on moment is provided, to realize power up function.Because portable apparatus is high for space requirement, in the situation of instrument finite volume, be difficult to realize the key circuit of many buttons, in order to solve problems, on market, a lot of instruments have adopted the pattern of single-button, can dwindle machine volume although it is so, but because single-button mode is in the situation that expressing multiple meaning, can only use the button length time to distinguish, this has just brought a lot of troubles to operating personnel, complicated operation, difficult memory, easily make mistakes, and under dangerous situation, do not have warning device to remind staff yet, most key part is easily water inlet also, instrument especially easily damages.
Summary of the invention
The purpose of this utility model is for overcoming the deficiencies in the prior art, provides a kind of affected simple, with browing record display screen easily, has a kind of Portable Detector of Carbon Monoxide of water-proof function.
The technical solution adopted in the utility model is: a kind of Portable Detector of Carbon Monoxide, comprise shell (1), LCDs (2), converter (3), microprocessor (4) and function button district (5), shell (1) upper right corner is provided with sensor (6), sender unit cap (7) is equipped with in sensor (6) outside, wireway (8) is connected with sensor (6), LCDs (2) upper left side is provided with audible alarm unit (9) and light alarming device (10), LCDs (2) lower end is provided with function button district (5), it comprises power key (11), function self check key (12), automatic calibration key (13), mode of operation key (14) and speech selection key (15), outer cover (16) is equipped with in outside in function button district (5).
Described LCDs (2) has character demonstration, instantaneous value, peak value, mean value demonstration, and shows with real-time clock, date and time.
Described light alarming device (10) refers to light flash when the harmful gas concentration that is measured at sensor (6) is higher than limit value, sends warning and reminds.
Described sender unit cap (7), is connected with shell (1) by screw thread, when detector is idle, plays a protective role.
The utility model has the advantage of: the utility model is easy to operate; small and exquisite comfortable; be convenient to carry; and can in severe field environment, carry out work; highly sensitive, function button district adopts waterproof case, plays the effect of protection key zone; distinctive warning device can detect hazardous gas under mal-condition and the sound that gives the alarm in time carrys out alert, and popularizing application prospect is wide.
