Overview

The pump suction phosphine detector can quickly and accurately detect the concentration of phosphine gas in the environment, and is generally used in grain warehouses. Filling grain warehouses with phosphine gas fumigation can kill pests, but phosphine gas is colorless and odorless. Inhaling phosphine can affect the human heart, respiratory system, kidneys, gastrointestinal tract, nervous system, and liver, so monitoring instruments are needed. The concentration of the fumigation process in the grain silo is generally selected between 0-2000ppm, and the residual concentration is generally selected between 0-20ppm.

Product Details

Pump suction phosphine detectorProduct Features

Waterproof, dustproof, explosion-proof, shockproof, intrinsically safe circuit design, anti-static, anti electromagnetic interference

Built in pump suction measurement, fast response, sampling distance greater than 10 meters, special gas path design

The 2.31-inch high-definition color screen displays real-time information such as concentration, alarm, time, temperature, humidity, battery level, charging status, etc

Large capacity data storage function, customizable for larger capacities. Supports real-time storage, scheduled storage, or only storing alarm concentration data and time, supports local viewing and deletion of data, and can also upload data to a computer through a USB interface for analysis, storage, and printing using upper computer software.

USB charging interface, can be charged with a computer or power bank, compatible with mobile phone chargers

Adopting a 4600mAh high-capacity rechargeable polymer battery, it can work continuously for a long time

Sound and light alarm, vibration alarm, visual alarm, undervoltage alarm, fault alarm, and multi-directional three-dimensional display of alarm status during alarm.

Alarm values can be set, and alarm methods can be selected from low alarm, high alarm, interval alarm, and weighted average alarm

It can be optionally selected to detect 1-4 gases simultaneously, with freely switchable units. Conventional gases do not require input of molecular weight, while special gases require input of molecular weight to automatically calculate and switch. Units can be selected: PPM, mg/m3, Vol%, LEL%, PPHM, ppb, mg/L

Three display modes can be switched: simultaneous display of four gas concentrations, large font cyclic display of single channel gas concentration, real-time curve, automatic or manual cycling between channels can be switched, whether to display large values, small values, gas names can be set, and historical curve graphs can be viewed.

Chinese and English interface selectable, default Chinese interface, concise Chinese or English operation prompts

Data recovery function, which can selectively restore or fully restore, eliminating the worries caused by misoperation

Record calibration logs, maintenance logs, troubleshooting strategies, sensor lifespan expiration reminder, and next concentration calibration time reminder function
