Product Description

Introduction
SPD205-TVOC tester is an economical professional instrument for detecting the concentration of total volatile organic compounds in the air, with a detection sensitivity of 0.01ppm, using a photo ionization detection sensor (PID). It is a broad-spectrum TVOC gas detector,
dopting 10.6eV violet lamp, can detect the total concentration of more than 100 volatile gases in the air, and can also detect the 
oncentration of a certain type of gas (When detecting a single type of gas, should set the calibration coefficient according to the 
as type, otherwise the error will be large. Even if the calibration coefficient is set, the error will be larger than testing the standard
 gas "isobutylene".). At the same time, it can also detect various data such as current ambient temperature value, real-time maximum concentration MAX, real-time minimum MIN, STE value, TWA value, etc., 
nd be suitable for environmental air pollution detection in factories, municipal buildings, school classrooms, conference rooms, and people gathering spaces . For specific values of calibration coefficients, please refer to the last page of the manual: 
"Table of calibration coefficients for various volatile gases under 10.6eV UV light".
