Product advantages:

1. Strong technology and excellent quality

The product is based on the technology of Jilin University's School of Chemistry, a pioneer in indoor air on-site testing in China, and a professional on-site testing instrument for quality production15 years.

2. Accurate and authoritative verification of detection

lParticipating in drafting of testing instrumentsJG/T 345-2011 "On site Testing Instruments for Indoor Environment of Building Engineering"; Formaldehyde detector participated in drafting industry or local standards such as DB22/T 2004-2014 "Air Formaldehyde On site Detector".

lThe on-site detection method for formaldehyde has been validated by national laboratories such as China CDC, Beijing CDC, and China Academy of Building Research.

3. Easy to operate and convenient to carry

Simplified operation instructions, no need for professional personnel, easy to operate, configured host, sampling aluminum alloy box, easy to carry.

4. Built in curve on-site detection

The principle of formaldehyde and ammonia detection originates from the national standard, and the detection steps are simple compared to the national standard. The instrument has temperature, pressure, and sampling volume data input functions, built-in curves, and combined with built-in formulas. After measurement is completed, it automatically displays the mass concentration of the substance to be tested under standard conditions.

5. Carefully designed sampling system

The sampler adopts a micro ultra stable sampling pump with stable power and a carefully designed built-in air circuit. The sampling performance is better than the national calibration requirements, and the stability is good.

6. Improve video quality after-sales service

Product configuration operation video, standard demonstration testing process, regular after-sales centralized follow-up visits in multiple regions across the country, testing training, and product verification.

7. Word of mouth selection with rich case studies

More than 10000 direct customers, accumulated rich experience in on-site instance testing, multiple testing solutions, suitable for on-site testing and experimental cabin comparison.

8. The "Multi parameter Air Quality Rapid Measurement Instrument" and "Bubble Absorption Tube" have obtained national invention patents.
