Summary:
Formaldehyde sensor can help customers monitor formaldehyde gas concentration. Now formaldehyde is actually divided into two kinds, one is paint, varnish, glue, paint and other high concentration of formaldehyde, these products will directly produce irritating smell, the newly renovated house will let people spontaneously escape this environment, so always said that the new clothes repaired, to ventilation for two months.
There is also a low concentration of formaldehyde, which can be said to be colorless and tasteless. Being in such an environment for a long time can also be uncomfortable. Because the volatile cycle of formaldehyde is very long, up to 3-15 years, even natural wood will use varnish for maintenance and good-looking, and varnish contains formaldehyde, so the newly renovated houses will more or less long-term release of formaldehyde.
Staying in an environment with high formaldehyde concentration for a long time may induce leukemia, so it is necessary to use a formaldehyde sensor to detect formaldehyde concentration. According to the national standard, formaldehyde content is less than or equal to 0.01mg/m2 is normal.
So how to choose formaldehyde detector? JXCT briefly explains the following formaldehyde sensor selection precautions.
Matters needing attention:
- Ensure the uniformity of formaldehyde sensor
If two or three sensors from the same manufacturer have been in the same environment for a certain amount of time, check to see if these values are consistent. If the difference is too large, it is difficult to guarantee the accuracy of the monitoring data. In the same environment and the same sensor, under no special conditions, the test results must be similar, otherwise it will be inaccurate.
- The minimum monitoring range should be low.
Generally what we monitor is the indoor formaldehyde concentration in the living environment, but its concentration is not high. Therefore, if the minimum test range is too high, it is difficult to respond to indoor formaldehyde concentration.
- Strong anti-interference ability.
If there is too much interference from other smells in the air, the formaldehyde test in the air is not accurate.
JXCT formaldehyde sensor, no approval, zero drift, strong electromagnetic interference resistance, with fixed mounting hole, easy installation. There are other series of formaldehyde detector, electrochemical formaldehyde sensor of high sensitivity, high reliability, suitable for wood building materials or after sterilization of residual concentration of formaldehyde detection and measurement.
