A formaldehyde multi-monitor that can measure the concentration n of formaldehyde with high accuracy and ease. It is a measuring instrument designated by the Minister of Health, Labor and Welfare [designation number 2301].
Formaldehyde is used in many familiar places such as preservatives, paints, furniture, and textiles, but it is not only an allergenic substance, but also classified as a carcinogenic substance.
We have commercialized a device that can measure the concentration of formaldehyde with high accuracy and ease.
Data saved in the main unit can be transferred to a PC using the included dedicated software.
This product is a measuring instrument designated by the Minister of Health, Labor and Welfare [designation number 2301].
- Three modes for “high accuracy”, “simple” and “various” measurements
- Consists of a portable monitor body and a small detachable formaldehyde sensor (43 x 17 x 4mm)
- Since suction is not required during measurement, measurement can be performed using only the formaldehyde sensor alone.
- Continuous monitoring of dynamics is possible while attached to the monitor body.
- Formaldehyde sensor can be used repeatedly
According to the indoor airborne chemical measurement manual provided by the Ministry of Health, Labor and Welfare, the sampling location should be set at a height of 1.2 to 1.5m, at least 1m away from the wall near the center of the room.
If you attach the monitor body to a tripod with a length of 1.2m as shown in the photo, it is possible. It is also possible to measure with the sensor alone. You can use it by attaching it to a tripod or hanging it from the ceiling.
Variation of measurement method
Normal measurement: Measured by attaching a formaldehyde sensor to the main unit
With the formaldehyde sensor attached to the monitor, it is possible to measure for 30 minutes or 60 minutes. The monitor itself is also small and lightweight, making it easy to move from one measurement location to another.
Multi-point measurement: Measure with the formaldehyde sensor alone and read with the main unit
Since the formaldehyde sensor can be used alone for measurement, multi-point simultaneous measurement can be easily achieved.
The monitor stores the initial value of the formaldehyde sensor in memory, collects it after on-site measurement with the sensor alone, and determines the concentration on the monitor. (Up to 250 items can be stored in memory.)
Multiple rooms can be measured with formaldehyde sensors, and measurements can be managed with a single main unit.
Continuous measurement: Measured by attaching a formaldehyde sensor to the main unit
Continuous measurement is possible with the formaldehyde sensor attached to the monitor. Changes in formaldehyde concentration over time and dynamics can be continuously monitored.
