1. Equipment overviewElectrochemical gas sensors mainly include carbon monoxide sensors, sulphur dioxide sensors, hydrogen sulphide sensors, ammonia sensors, etc. The zero point and sensitivity of the sensors will inevitably drift during use. In order to obtain more accurate measurement values, it is generally required to calibrate the sensors before measurement, and the equipment used is the electrochemical gas sensor calibration chamber.
(1) Based on the actual demand for calibrating a large number of temperature and humidity meters, a three-sided observation window is designed, which can calibrate multiple tested products at the same time. The calibration efficiency is extremely high. Currently, there is no similar product in China that can match it.
(2) The design of double operating holes on the box allows the verifier to put his hands deep into the box and directly adjust the instrument under inspection in the box, which greatly improves the verification efficiency.
(3) The unique uniform temperature field design not only meets the requirements of the new regulations for low-temperature and low-humidity temperature calibration chambers, but also ensures that the temperature uniformity is less than 0.3°C.
(4) Ultra-thick thermal insulation layer and three-layer vacuum glass for the observation window, which prevents cold and heat from being lost, ensuring rapid and stable temperature rise and fall.
(5) Automatically scheduled power on, so that the equipment can be automatically powered on before going to work, and readings can be taken immediately after going to work, saving working time.
(6) High-quality controller, high product quality and performance.
(7) This equipment not only has a wide humidity range, but also has a large working room volume of 300L. It can detect more than a dozen temperature and humidity instruments at the same time, which greatly improves the detection efficiency.
(8) The whole machine adopts an original vortex distributed rectification method, with multiple fans and multi-point parameters controlling uniformity, replacing a single fan and improving the overall temperature and humidity performance.
(9) The new technology developed can realize the communication function between the dew point meter and the calibration box display screen, and the calibration box screen can simultaneously display the dew point meter test data, saving time for testing work.
