The HH40 series has been discontinued. Please see the HH42A as a possible alternative or contact our Temperature Engineering department.
The Model HH41 handheld
thermistor thermometer is a rugged,
field tested unit that fits a wide
variety of temperature measurement
applications requiring ultra-high
accuracy and high resolution at an
economical price. The HH41
accepts OMEGA’s 400 Series
thermistor probes with phone jack
termination. The HH41 features
display hold and °F/°C selection
from the single front panel tactile
feedback silicone function button.
The unit’s LCD display features a
low battery indication and also rate
of temperature change arrows
which, flashing at different speeds,
inform the operator of the rate at
which the temperature is changing.
The unit has internal jumpers to
disable selection of °F or °C from
the front panel and enable display of
either °F or °C only. Internal jumpers
are also present to select either
auto or manual shutoff mode.
In the auto shutoff mode, the unit
will automatically shut off 10
minutes after the last function key
entry. Model HH42 has all the
features of the HH41 with the addition
of RS-232 communications.
In situations where very high system
accuracy is required, OMEGA offers
a total system calibration service
(probe plus meter); ask for CAL-4.
