1、 Adopting standards

HJ/T 375-2007 "Technical Requirements and Testing Methods for Environmental Air Samplers"

JJG 956-2013 "Atmospheric Sampler"

2、 Product advantages

Using electronic flow meters for more precise flow control

◆ Mold anti reverse connection design, anti reverse suction dryer protection instrument

◆ Purpose: Suitable for collecting various harmful gases in ambient air using solution absorption method

3、 Product Features

◆ Imported brushless pump with ultra-low frequency for smoother flow;

◆ Efficient air path filtration and dehumidification protection device;

◆ Built in high-efficiency lithium-ion battery, with a continuous working time of more than 5 hours;

Equipped with an anti backflow suction dryer inside the machine to prevent liquid backflow;

Efficient noise cancellation function, achieving ultra-low noise operation;

◆ Capable of measuring on-site environmental temperature, automatically starting absorption bottle constant temperature heating at low temperatures;

◆ Flexible sampling method:

Four channels can be sampled simultaneously, or any single channel can be sampled, and each channel can be individually controlled;

◆ Automatic control of sampling flow:

Adopting four electronic flow meters, the microcomputer system detects the sampling flow rate and automatically controls the sampling flow rate to the set flow rate

Point, automatically compensate for flow changes caused by voltage fluctuations and resistance changes;

◆ Automatic calculation of sampling standard volume: Automatically accumulate sampling volume and convert standard volume based on air pressure and temperature

Sample volume;

Equipped with RS232 digital communication interface, it can be connected to an external printer for convenient data output;

◆ Equipped with real-time clock function, it can pre-set sampling and start sampling on time, reducing labor intensity;

The sampler automatically monitors the power status and has a power-off memory function during the sampling process. Automatically save work hours during power outage

According to the report, the sampling before the power outage can be restored after the call is received;

Connect four pipelines with rubber tubes of different colors to easily and accurately connect the air circuit;

128 × 64 low-temperature resistant LCD display screen.
