This product is no longer available for sale.
The HHM1
digital multimeter/ thermometer is a full function digital multimeter,
which also features dual type K thermocouple inputs and voice
annunciation of measured values. This compact, portable meter
measures true RMS ac voltage and current, as well as resistance
and temperature, and will accept any two type K thermocouples
terminated with miniature SMP connectors. Whether in the laboratory
or on the run in the field, the HHM1 user never has to look at
the display to obtain readings.
The HHM1 features a standard voice annunciation used to verbally
tell the user the current measurement in a choice of five different
languages. This unique speech feature will continuously announce
measurements, may be operated manually with the push of a button
to speak on demand, or may be disabled. The HHM1 displays measured
values on an easy-to-read LCD for visual indication, which also
includes an indication of the current measurement function, the
other available measurement functions, speech function status
(continuous, on demand or off), measurement units, thermocouple
probe input (T1, T2 or T1-T2), display hold and low battery. All
DMM connections plug into the front of the unit. Thermocouples,
earphones and the ac adaptor plug into the rear panel of the unit.
This rear panel also contains a three position volume selector
switch.
On top of the HHM1 meter is an on/off switch along with six pushbuttons
used to select from a variety of unique additional functions.
These include a "TEMP" function, which selects the thermocouple
input T1, T2 or the differential. The "OHM ZERO" function
compensates for the resistance of the test leads for resistance
measurements. "DISPLAY HOLD/SPEAK" selects continuous
or on demand speech or freezes the display. The "SPEECH"
button turns the speech function on and off. "ºF/ºC"
switches the temperature units. "AC/DC" similarly switches
between ac and dc measurements.
Included with each HHM1 is a set of test leads for measuring voltage,
current and resistance. The red lead handle includes a convenient
pushbutton to easily operate the speech function while holding
the leads. An optional piston grip type K thermocouple handle
is also available with a similar pushbutton to activate the voice
function remotely for temperature measurements. This handle accepts
both standard OST and miniature SMP type thermocouple connectors.
