Precautions before using the phosphine detector

Tiandi first and introduce the precautions before using the phosphine detector

Phosphine is a colorless, highly toxic, flammable liquefied compressed gas stored in a cylinder. The storage pressure is 522 psig (70 °F) at a vapor pressure. The gas is heavier than air and has a smell like a stinky fish. If a hydride containing other phosphorus such as ethyl phosphide is encountered, it will cause spontaneous combustion. Phosphine should be treated as a highly toxic and pyrophoric gas. Inhaled phosphine can affect the heart, respiratory system, kidneys, gastrointestinal tract, nervous system and liver. Wear self-contained breathing apparatus (SCBA) and full-body fire-fighting clothing in areas where the concentration of phosphine exceeds the standard. Persons entering areas containing flammable gases are aware of the very serious fire and explosion hazards.

It can be detected by our portable phosphine detector, with high speed and high precision.

● Waterproof splash, dustproof, explosion-proof, shockproof, intrinsically safe circuit design, antistatic, anti-electromagnetic interference

● Built-in water vapor and dust filter to prevent damage to sensors and instruments due to moisture and dust

● Built-in pumping measurement, rapid response, sampling distance greater than 10 meters, special gas path design, can directly detect negative pressure or positive pressure -0.5 ~ 2 kg of gas, no impact on the measurement results

●2.31 inch high-definition color screen displays real-time concentration, alarm, time, temperature, humidity, storage, communication, power, state of charge, etc. The menu interface uses HD simulation icons to display the function names of each menu.

● Large-capacity data storage function, with 100,000 data storage capacity as standard, and larger capacity can be customized. Support real-time storage, timing storage, or only save alarm concentration data and time, support the machine to view, delete data, also upload data to the computer through the USB interface, use the PC software to analyze data and store, print.

●USB charging interface, can be charged by computer or charging treasure, compatible with mobile phone charger, overcharge, over discharge, over voltage, short circuit, overheat protection, 5 level accurate power display, support USB hot plug, detector can be normal when charging Work, optional RS485 communication

●Using 4500 mA large capacity rechargeable polymer battery, it can work continuously for a long time.

● Sound and light alarm, vibration alarm, visual alarm, under voltage alarm, fault alarm, multi-directional stereo display alarm status when alarming.

●Alarm value can be set, alarm mode can be selected as low alarm, high alarm, interval alarm, weighted average alarm

●High-precision temperature and humidity measurement (optional), temperature compensation of the sensor at the same time, the instrument uses a temperature range of -40 to 70 degrees, can detect 400 degrees of gas, higher temperature gas detection can be customized (optional high temperature sampling and cooling) Filter handle or high temperature and high humidity pretreatment system)

●It can be equipped with 1~4 kinds of gases at the same time. The unit can be switched freely. The conventional gas does not need to input molecular weight. The special gas needs to be input and the molecular weight is automatically calculated and switched. The unit is optional: PPM, mg/m3, Vol%, LEL%, PPHM, ppb, mg/L

●Three display modes can be switched: display four gas concentrations at the same time, large font cyclic display of single channel gas concentration, real-time curve, automatic cycle between each channel or manual cycle can be switched, can set whether to display the maximum value, minimum value, Gas name, you can view the history curve.

● Chinese and English interface can be selected, default Chinese interface, concise Chinese or English operation tips

●Data recovery function, can be selectively restored or fully restored, eliminating the worries caused by misuse

● Zero point automatic tracking, long-term use is not affected by zero drift.

● Three-level calibration of the target point to ensure the linearity and accuracy of the measurement, and can meet the national standards and local metrology bureau standards.

● Concentration calibration misoperation automatically recognizes and blocks, avoiding the defects caused by human factors.

● Real-time detection or timing detection (for the case where the amount of gas to be measured is relatively small), the pump can be turned off to prevent the startup time when not detecting.

●Can record calibration log, maintenance log, fault resolution countermeasure, sensor life expectancy reminder, next concentration calibration time reminder function
