FOR DUCTS & SMALL AREAS The HkIP 233 has been engineered for use particu- larly in smali, tight spaces including cha111bt.1-s and incubators. as \\-ell as typical Ion- temperature duct applications. Its s~nall sensor head with its small rl~ermal Inass is an :id\.antage especially in situations u.11ere the sensix head must respond cluickly to s.11-rounding temperature changes. ,413 optional kit consisting of aluminum fl snge. lead-through piece, and steel support l x r enables installation of the HMP 233 in ducts. channels, and through m-rills.

RELIABLE MEASUREMENT This ir.stnin:ent incorporates the H-sensor n.hich measures Ilu~nidity more accurately (up to f 1%) and reliably than other sensors. Its tolerance to high temperature, ability to operate in condensing enviro~~ments. resistance to Ilarsh chei~~icals and contaminanrs. and excellent long-rerm stability are of great value in accuratel>- rnonirol-ing and controlling chanlbers. processes, ctc. The IlhIP 233 transmitter is fully rernpcrature compensated and pro\-ides ullsul.passed zccrracy 01-er the entire Iiulllidity range (0 to 10094) RHI.
