Performance characteristics: Measurement through HF electromagnetic sensing. 10 different at option. Automatic temperature compensation. Setting of upper limit of moisture content ratio, prompting of overrunning. Ultra-large LCD ensuring clear readings. Automatic prompting of low voltage.

The gas leak detector can be used in the natural gas is leaked indoors and outdoors, where the gas is produced, stored, used, etc., such as chemical, petroleum, metallurgy, oil depot, LPG (Liquefied Petroleum Gas) station, gas transmission and distribution, etc. to detect the leakage and show the leaking concentration or explosion percentage with a digital display. This device can set two-level alarming value. The detector can rise the acousto-optic alarming when the detected concentration reaches the preset value. It adopts high sensitivity sensor from Japan Figaro. The meter’s function is powerful. It also can synchronously measure that time’s temperature and humiditywhen measuring methanegas.

RTD thermometer is  mainly using for monitoring high-precision temperature and measuring scopes, the thermometer can display changes among the three units :Kelvin, Fahrenheid and Centigrade, and it aslo has memory, reading the MAX and MIIN values function . Measuring range : from -200~600℃.

Noncontact measuring. White backlight LCD. D:S=10:1. Auto-data hold and auto-turn off (Auto turn off after 15sec. when release the button). A great many of emissivity symbol. Use abroad: can used for food, safety-inspect， fire inspect, power vehicle and diesel engine,
plastic factory etc. Can select °C/°F. Resolution: 0.1°C(0.1°F).

Adopting a detector powered by a silicone photocell with high stability, photostability, and shock resistance, strict vision correction and accurate photometric measurement can be realized. With a wide measuring range, it can measure between 0.01-39990cd/m2 without a dimmer. It is a digital display with good indication reproducibility, data latching and peak value latching functions;  With very low power consumption, it can operate continuously for 100 hours on a 9V layer-built battery;  Mini light probe, measuring angle
