CALIBRATABLE MULTI-FUNCTION PSYCHROMETERS –
EP8703, EP8709, EP8710
Ideal for accurately measuring any environment’s temperature, relative humidity (RH),
dew point and other condensation parameters.
FEATURES:
• Jumbo backlit display with double (EP8703,
EP8709) or triple (EP8710) readout
• Field calibratable using optional 33% and
75% salts
• Data hold and Max/Min buttons (EP8709 and
EP8710 only)
• Also calculates and displays wet bulb
temperature (EP8709 and EP8710 only)
• Using included external probe (EP8710 only),
can also measure: 1) the difference between an
object’s internal and surface temperatures or
2) an object’s condensation temperature—the
difference between its surface temperature
and the dew point temperature
