thermometers are the most commonly used temperature measuring instruments in
the food industry. They are easier to read than glass thermometers,
generally more accurate than the older dial-type thermometers based on
bimetal coils, have a great range of specialized uses and applications and
tend to have a much quicker response-time. Digital probe thermometers
are generally of two types: thermocouple digital thermometers and thermistor

digitals generally have "built in" probes and sensors. They
must be calibrated during the manufacturing process and so are not
interchangeable. Thermocouple digitals, with some exceptions, can
accept any matching category of probe (the two most common are K-type and
T-type--these have different temperature ranges). We concentrate on
K-type only, since this type spans all food application temperatures, and
has more availability of probe options.
can be very good with both types, but thermistor digitals are limited to the
type of built-in probe they come with, and if the probe breaks, you have to
buy a new thermometer.
digital thermometers are generally very predictable in their quality, and
the response characteristics of their fitted probes is within a very narrow
range. All QA stocks the highest quality thermocouple digital thermometers,
so they can be used with high confidence.
digitals are made worldwide, and can have variable quality, if not carefully
checked. All QA performs checks of all of their thermistor-based
products to ensure that their customers are getting products of excellent
quality. Our line of thermistor products represents the very
best available at the price.
This new pocket digital unit is the most
useful food preparation tool we have found to date. It is
completely waterproof, accurate and tough, has user-calibration, and can
be used for dishwasher temperature monitoring.
Economy Digital Thermometer
QA offers this hand probe unit as an alternative to the familiar bimetal coil
thermometer used for food preparation. The upward facing dial allows a
convenient viewing angle. Light and easy to use.
Digital Refrig/Freezer Thermometer
This digital mounts on the wall or stands
on the counter and displays max-min data and also sounds an alarm
when a preset temperature is reached. This unit also is
available with a glycerol bottle sensor to simulate true food
temperatures (AQA 1281)
Digital Time-At-Temperature Thermometer
This countertop unit
allows cooking by time, temperature reached, or both. When
cooking is complete according to the setting, the alarm sounds.
Magnetic base keeps the unit secure. Can also be wall-mounted.
Once you use this unit, you will not want to be without one.
Easily seen 1 1/8''H display digits. Probe in Freezer
or Refrigerator. Constantly displays temperature of exterior air plus
interior. Cable is small to run between door gaskets. Min/max probe for
ice bath chill-down or water bath thaw.
This display digital
thermometer can be used near washing areas, over steam kettles and
with ice or water baths. Mount on the wall or stand on counter.

Sensing Digital Thermometers
See our IR Thermometer Information Page
| IR Thermometer Listing with Ordering
digital thermometers sense temperature from a distance. The radiation
of infra-red ("IR") light from surfaces is related to the
temperature of the object--you cannot see this heat radiating light, but the
IR thermometer can see it. The IR thermometer "sees" the
intensity of this light and converts it into an equivalent surface
sensing is needed when speed, numerous reading, and necessary distance from
the measured object are requirements. If you can't reach it to make a
surface reading, or if you need to scan hundreds of areas in a short period
of time, then an IR digital thermometer is what you need.
key to IR thermometry is to make comparisons between what you get with the
IR "gun" and what you get with a direct touch reading at the
surface or a penetration reading within the object. IR readings can be
misleading, since they can also "see" air temperatures and also
they only look at the thin outer skin temperature of a target
object. With care, however, the advantages of using a gun are
tremendous--you can make dozens of measurements in a minute or two--the only
limitation is getting to one measurement location to another.
QA offers the best selection of IR digital thermometers available
anywhere--from simple and very inexpensive devices to the best of laser
sighted and regular IR guns.
