Formaldehyde (HCHO) - CO__Combustible__H2S__O2

The Riken Keiki FP-31 is a highly sensitive portable gas detector specific for formaldehyde detection. It uses a photoelectric photometry method which utilises colourimetric tablets for detection. A tablet is placed into the instrument, and then a room air sample is pumped onto the tablet for either a 15 minute or a 30 minute period. If formaldehyde is present, it will cause the chemically impregnated tablet surface to darken or stain. The magnitude of the stain directly correlates to the level of formaldehyde in the air. The stain darkness is read by an optical sensor in the FP-31, and then the instrument calculates the formaldehyde concentration. The FP-31 then has a direct readout of the formaldehyde measurement on an easy to read LCD display. The unit is capable of detecting deficient levels of formaldehyde, to confirm if an area contains safe breathing levels.

The Riken Keiki GX-3R is the smallest and lightest 4 Gas Confined Space gas detector available today. With a size of 58 mm wide, 65 mm high and weighing 100g, the Riken Keiki GX-3R gas detector can be defined as true craftsmanship. The Riken Keiki GX-3R is perfect for confined space work as its size means it does not interfere with work even if it is attached in the breathing zone. Battery Life: The Riken Keiki GX-3R gas detector has a build-in extended battery mode which allows the monitor to be used continuously for up to 40 hours before recharging. IP66/68 compliance, as well as a three-year sensor warranty, allows the Riken Keiki GX-3R to be used with confidence. Alarm: The GX-3R has 3 preset alarm settings per gas and an over alarm which allows the alarms to be set at EH40 workplace exposure limits plus an additional alarm for a higher detection range. The GX-3R internal data logger allows 3600 event logs and 300 hours which can be read out using an IrDA link. A loud 95dB alarms buzzer is also included. Operating temperature range: The Riken Keiki GX-3R has an operating temperature range of -40 degrees Celcius to +60 degrees Celcius (intermittent) or -20 degrees Celcius +50 degrees Celcius (continuous) allowing the GX-3R to be used in many different environments and applications. The GX-3R uses 3 compact sensors including a brand new Electrochemical Oxygen Sensor. The Riken Keiki GX-3R Confined Space Monitor will detect, Combustibles, Hydrogen Sulphide, Oxygen as well as Carbon Monoxide. A 3-year sensor warranty is now standard.
