 Digital Panel Meters


Temp, Inc. has the most extensive line of Digital Panel Meters available
on the market today.  If it is not available in our standard models, we can usually provide
a custom design for your exact requirements!


Temp, Inc. can provide Digital Panel Meters
and associated equipment in NEMA-wall mount,
floor mount, or portable enclosures per your requirement.



Standard models are available for AC and DC current and voltage
Our digital panel meters are designed to take the place of standard analog panel meters where a reliable, single range meter with increased accuracy and visibility is required at a comparable cost and no programming is required.

 Models are also available to operate from Electrical Transducers
 (see Temp, Inc.Transducers page) where  remote monitoring  of process variables are required.

All AC Ammeter models have
a 0-5 amp signal input range for direct connection to current transformer with 5 amp secondary.  List price: $195.00
Add $45.00 to price for matching current transformer  Add $ 95.00 for 300-400 amp current transformer

#Note: Model AA-10 has a range of 0-10.00 amps for direct measurement of A.C. current without a current transformer.

#Note: These specifications are for all M1 Series of Digital Panel Meters i.e
M1-AA, M1-AV, M1-TC and the M1-RR which accepts a 4-20ma input.

These meters represent the latest and most advanced techniques for monitoring and control in
AC power systems.  These True-RMS meters are especially useful in monitoring voltage and
current supplied to motors or heaters by an SCR Power Controller.
There are two models: AC Voltmeter and AC Ammeter.  The 4 or 4 1/2
digit display plus programmable keypad sealing capabilities allow these
meters to be used in most industrial and laboratory applications. 
Optional RS485 Serial communications or 4-20ma analog output allows
for remote control, recording or computer interface.
The dual output relays are ideal for Hi/Lo alarm or ON/OFF control. 
The operating point of the relays is settable from front keypads.  The standard ranges available
are 0-5 amp AC and 0-600 VAC but other ranges and d.c. models are also available.
