OMEGA’s lightweight, portable 5830 digital
thermistor thermometer provides precision
temperature measurement, accuracy and
high repeatability. With five sensor inputs
(Series 400 or 700 probes), the 5830 is
extremely versatile. Any of the five
temperatures can be displayed by touching
the appropriate panel switch. In addition, the
5830 displays maximum, minimum, average
and differential temperatures. Two models are
available: the 5830 features 0.1° resolution,
while the 5831 has 0.01° resolution.
5830, $890 with OL-705-PP air probe, $73,
