Which school Excavator strong, Riken FP-30 Formaldehyde detector

Riken FP-30 Formaldehyde detector Description: This product is manufactured in Japan. No electrochemical sensor, instead of using photovoltaic principles, combined with tablet reagents with long life, high precision, the disadvantage is detected for a long time, the market is still the best-selling formaldehyde detector, the Japanese market sales of the first Japanese home decor Public environmental monitoring formaldehyde first brand! Riken FP-30 Formaldehyde Detector Product Features: * Install only detect the tablet can easily detect * Terms and reliable self-diagnostic function * included with automatic storage of measurement data (99) and can be downloaded to the PC * No warm-up time * Automatic backlight display * resolution can reach 0.005ppm (the highest resolution instruments on the market) Riken FP-30 Formaldehyde detector technical parameters: Detection principle test paper photoelectric spectrophotometric detection range 0 ~ 0.4 ppm (TAB No. 008) 0 ~ 1.0 ppm (TAB No.009) detection time of 30 minutes (1800 seconds) 15 Clock (900 seconds) Resolution 0.005 ppm 0.01 ppm detection mode detector within the TAB mode (time plus the calculated value measured) concentration representation LCD Working environment -10 ~ 40 ℃; 90% RH or less (non-condensing) Memory function test point: 99 points (the determination is completed, automatic storage) Self-diagnostic function and by bad light, the battery voltage is low, bad pump system optical unit anomalies abnormal temperature alkaline batteries power four continuous use time about 12 hours (alkaline batteries, no lighting, no alarm, 20 ℃) ??Dimensions approximately 85 (W) × 190 (H) × 40 (D) mm (removed protrusions) Weight Approx. 500 g (host, including the battery) Riken FP-30 Formaldehyde detector standard accessories: Detection tablet TAB (20 / pack) * Carrying Case * alkaline battery * Operating Manual * Certificate Riken FP- 30 formaldehyde detector Optional accessories: * detection tablets (20 / bag) * dust filters * Output printing software * Output dedicated cable * tripod Riken FP-30 Formaldehyde detector test principle: the test paper photoelectric spectrophotometry: When When the gas is blown onto the detection TAB, TAB grouped together and impregnated with hair color toner and paper will be from a chemical reaction. Such as formaldehyde and followed the correct paper in a paper containing the reagent will form a compound with formaldehyde, the color will turn yellow from white. It reflects the degree of discoloration suffered light amount of reflected light. Strength rate of change of the amount of reflected light as a gas concentration can answer work. Preset calibration curve to determine the concentration of the gas can be detected by gas response value
