Reacts only to hydrogen, no false signals! Initial detection speed is 1 second!
The HY-ALERTA 500 model from H2scan is a portable hydrogen leak detector that can instantly detect a wide range of hydrogen concentrations. The LED at the tip of the sensor probe allows for visual confirmation of hydrogen levels. Its lightweight and compact design ensures reliable detection of leak locations.
It is a high-performance air suction pump that is compact, lightweight, portable, and equipped with a constant flow function and a cumulative flow function.
The Mini Pump MP-Σ (Sigma) NII series is a compact, lightweight, portable, high-performance air suction pump equipped with an integrated cumulative flow measurement function. There are models MP-Σ30NII, Σ300NII, and Σ500NII for different flow ranges, as well as a high-pressure loss type, MP-Σ100HNII. With stable suction flow, it can be widely used for sampling harmful substances in work environments, indoor environments, and atmospheric environments. The inclusion of a lithium-ion (rechargeable) battery allows for long operating times. 【Features】 ○ Instantaneous flow and cumulative flow displayed digitally ○ Constant flow function → Suppresses flow reduction due to increased suction pressure ○ Timer sampling with 4 modes → Manual, countdown timer, volume timer, cycle timer ○ Large, bright LCD display with backlight ○ Measurement data recording function → Allows confirmation of the last 10 measurement results via communication with the main unit and a computer For more details, please contact us or download the catalog.
For measuring air volume in clean rooms and offices! Suitable for measuring large supply and exhaust vents.
The testo 420 is a lightweight hood air flow meter weighing 2.9 kg. It can be mounted on a dedicated tripod. To accurately measure air flow even in large ventilation ducts, it is equipped with a straightener inside. Additionally, with the built-in differential pressure sensor, it can also be used as a differential pressure gauge by connecting a pitot tube. 【Features】 ■ The straightener smooths out turbulence inside the hood ■ Lightweight at 2.9 kg, comes with a convenient carrying cart ■ The main unit can be removed for differential pressure measurement ■ Maximum and minimum value display ■ Memory function (can continuously record for up to 15 minutes), can be connected to a PC *For more details, please download the PDF or feel free to contact us.

Radiation balance meter
The radiation balance meter MC8P-NET07D measures radiation balance in the near ultraviolet and far infrared wavelength ranges. The upper surface of the radiation balance meter detects solar radiation and long-wave radiation from the sky (clouds), while the lower surface detects solar radiation reflected from the ground (albedo) and long-wave radiation from the Earth, measuring the difference as the radiation balance.
You can check the individual exposure status of chemical substances with a trend graph. (Optional use)
● Supports 17 major chemical substances, including toluene. You can select the target substance from 17 types of chemical substances. When the concentration of the selected substance in the air reaches the alarm level (TWA, STEL), it will notify you with a buzzer or lamp. ● Real-time confirmation of the instantaneous value, average value, TWA value (time-weighted average), and STEL value (short-term exposure limit) of the chemical substance concentration in the air. * TWA value (time-weighted average) The time-weighted average concentration of harmful substances that is considered not to adversely affect the health of most workers when exposed repeatedly during normal work of 8 hours a day or 40 hours a week. * STEL value (short-term exposure limit) The concentration of harmful substances that does not adversely affect the health of workers if they are exposed continuously for 15 minutes and their daily exposure is below the TWA value. ● Compact and lightweight, it does not interfere with work. ● Built-in NFC for easy data reading. It can be easily imported using the log data collection set (optional).
