2 A = 780248 (disposable particulate filter), B = 1830-0055 (filter membrane 0235-1072 must be replaced every 30 days), C = 1991-0147 (disposable filter for corrosive gases)
Outside of RH range:
3 Tends to have lower response at higher humidities.
4 Tends to increase sensitivity at higher humidities (due to the chemistry of the reaction).
5 Tends to under-report at higher humidities (typically >75% RH) due to the gas characteristics to adhere or decompose on contact with water/moisture. The response seems to be lower but the actual gas concentration under these high humidity conditions will be lower than
expected.
6 Tends to under-report in dry conditions (<25-30% RH).
7 Depending on the combination of temperature and humidity, even within the ranges specified above, a detector’s performance efficiency can be influenced due to condensation, physical tape material changes, or optical changes. Consult Honeywell Analytics’ Service Department.
8 Refer to TechNotes 971131 (Chemcassette
® -based Instrument Accuracy and Precision) and 1998-0219 (Protocol for Testing Gas Detectors).
9 Slow recovery: Prolonged exposure to high levels of gas/vapor (2x TLV or above) can condense in the system and may require purging with dry clean air or inert gas.
10 For information about the expiration date of the Chemcassette, refer to “Chemcassette” on page 40 (Review menu).
11 The number of days from the installation date that the Chemcassette cartridge can be used. When the allowable-days limit is reached, or if the absolute expiration date (printed on cartridge) is reached, the detector will issue an Expired Chemcassette Cartridge fault. The type of
expiration is found in the event history data field for the fault (either 1 [stale] or 2 [expired]). Replace the cartridge when this fault is issued. The only exception is if the cartridge was used only briefly and then removed from the detector and properly stored in the sealed bag at the
recommended temperature. In this case, the cartridge can be used past the stale-tape date (but not past the absolute expiration date) by clearing the stale-tape fault before going into monitor mode. Advance the tape manually about five inches before installing the cartridge and
entering monitor mode.
12 Do not use the optional sampling wand for those gases with recommended sample tubing lengths of less than five meters and no recommended sample line particulate filter.
