Formaldehyde is a poisonous gas, and it is extremely necessary to measure the formaldehyde content. What are the instruments for measuring formaldehyde? Today, PChouse will answer them all for you.
1. Probe tester
Representative instruments include XP-308, 4160, PPM400, etc., which are characterized by direct data reading and easy to carry. The disadvantage is that they are greatly affected by temperature and humidity. , need to be calibrated with standard gas, and the probe is generally replaced every year.
2. Formaldehyde tester that uses spectrophotometry to perform analytical readings
? There are Japanese Riken FP-30 and domestic Kyrgyzstan Big Swan. The former uses finished tablets, and the instrument is compact and easy to sample. It will read directly after 15 to 30 minutes, and the accuracy can reach 0.005PPM. The cost of maintenance is that the price of tablets is about 17 yuan/tablet, and the machine does not need maintenance at all.
? The relative operation of Little Swan is relatively complicated. The steps required after 15 minutes of sampling are cumbersome. The accuracy can be 0, 01. The characteristics of this type of instrument are also outstanding: high precision and little impact from interfering gases. , temperature and humidity are compensated.
3. Handheld formaldehyde detector
? It is a handheld instrument that can continuously measure formaldehyde. This product is suitable for environmental monitoring, industrial production, chemical industry and other places where formaldehyde is present.
4. Portable formaldehyde detector
? It can be set to zero at the measured site without using outdoor air. Used in indoor formaldehyde gas detection in public places, indoor formaldehyde gas detection in civil buildings, and formaldehyde content detection in building materials
