The Dynalco TMP-100 Multi-Point Digital Pyrometer is a high quality 19-channel temperature indicator powered by two 9-volt alkaline batteries. This digital temperature monitor accepts grounded and ungrounded thermocouples of the same type depending on model. It also has 3-1/2 digit display, brightness increases with ambient light.
Some versions accept all 100 ohm platinum RTDs. Integral cold junction compensation. ABS type approval. CSA approval: Cls I, Div 1, Grp C & D with approved 9-volt batteries.
Digital readout with 1° resolution.
Intrinsically safe. Third–party approved. No expensive hazardous enclosure required.
Heavily gold-plated selector switch for long life, trouble-free operation.
Integral 2-pole selector switch permits using grounded or ungrounded thermocouples.
Requires no external dc or ac power.
Fits existing cutouts and mounting holes of other popular pyrometers.
Compensation for lead lengths or lead resistances not required; use inexpensive small gauge thermocouple extension wire and save cost and
Fully gasketed; rugged construction.
Readout unaffected by power line noise and spikes (no line connections).
Part No.: TMP-100
Display: 3-1/2 digit (–999 to +1999), 0.5" high, liquid crystal display, 1° increment. Brightness increases with ambient light (no outdoors fadeout). Open thermocouple or RTD indicated by a number 1 in the thousands column; all other digits blanked. Momentarily pressing the front display push button activates the display for 50 seconds.
Environment Temperature: 0°F to +165°F (–18°C to +74°C); 0.25% maximum effect on readout.
Selector Switch: Two-pole, 19-position, double gold plating of contacts.
Sensor: Thermocouples: Grounded or ungrounded; integral cold junction compensation. Thermocouple extension wire resistance of up to 100 ohms introduces less than 1° error. RTDs: Accepts 2-wire RTDs only. Use with heavy copper extension leads to minimize error, i.e., 16 AWG for up to 50 feet, 14 AWG to 100 feet.
Power: Two common 9-volt batteries such as Mallory M1604HD2, Eveready 1222, Ray-O-Vac D1604. Battery life is approximately 4000 viewings,
or a couple of years, under typical operation. Appearance of decimal points after every digit indicates discharged batteries.
