HTV-M PPM record type formaldehyde detector product introduction
Type HTV-m formaldehyde detector of British PPM company, using the most advanced microelectronics and sensor technology, with humidity compensation function, can accurately measure the formaldehyde concentration even in HTV-m type high temperature and high humidity under extreme environment. The readings are displayed in ppm or mg/m3 units. Temperature and humidity can be measured in real time. PPM company supplied for formaldehyde staris calibration, the user can for the tester for field calibration and periodic calibration, increase detection precision of detection instrument. HTV-m is the basic type (HTV) on the increase of data memory and real-time clock function, with using a AC adapter, can detect online data recorded continuously for 7 days, make HTV-m become a continuous monitoring and data recording function of formaldehyde detector. Function is far superior to other products on the market.
HTV-M PPM record type formaldehyde detector product features:
Not affected by the extreme high temperature and humidity environment, with the function of humidity compensation
Formaldehyde unit display: ppm or mg/m3 (0 C and 1 atmospheric pressure standard conditions)
One touch operation, fast sampling, fast recovery time
Standard configuration includes a formaldehyde source (valid for six months), just a few seconds to complete the calibration procedure.
The effect of phenol on the reading was eliminated by 10 phenol filters.
Optional accessories SPC-2 computer remote control software and adapter, so that the formaldehyde detector has become a wireless monitoring system
Has been 9001:2000 ISO quality certification, and in line with the CE standard

Resolving power
0.01ppm (another 0.001 ppm)
accuracy
2%, according to 4-5 repeated measurements in 12 Taiwan formaldehyde analyzer, and the results of Statistics:
Accuracy
10%, according to the provisions of the United States NIOSH, measuring method of acceptable use, measurement of formaldehyde concentration relative humidity ranged from 0.3ppm in 25-70% environment. The acceptable standard of NIOSH is the result of the data which is about 25% of the true value in the 95% confidence region. PPM formaldehyde detector can achieve the standard NIOSH. You
