It’s simple to operate! SILO•CHEK is easy to operate with high accuracy and selectivity to phosphine. The sensing element is not interfered with by co-existing substances which have previously caused reading errors in other fumigation monitors. It is robustly built into a small ABS enclosure with a large easy to read LCD display. Its response is linear to phosphine gas and has a monitoring range of 0-2000ppm. This automatic pumped version is supplied ready for use in a padded vinyl pouch with belt/waist loop together with inline dust filter, tubing connector, calibration tool, 9VDC alkaline battery and instruction manual. SILO•CHEK is suitable for use with the latest fumigation systems available and will read accurately down to 1ppm even when carbon monoxide may be present in grain which has been stored for several months. SILO•CHEK will pay back the grower quickly when used frequently during fumigation “on-farm” by allowing the grower to minimise the amount of gas used whilst maximising efficiency of the process.
