THERMOST The TB300M bath is an instrument used to calibrate transducers, RTD and temperature-
measuring sensors in the field and in the laboratory. The possibility to generate
positive and negative temperature ramps makes it suitable for use in calibrating and
testing thermostats.
TECHNICAL CHARACTERISTICS
The TB300 M bath consists of a stainless tank with capacity of 10 litres, useful height 340
mm and diameter 85 mm. The bath is equipped with a stainless steel mixer with electrical
motor power, a safety thermostat, drain cock and overflow drain pipe.
TB300M is equipped with a new PID microprocessor
controller with a resolution up to
0.01°C, setting of the standard of measurement in °C/°F, programming of ascent/descent
ramps and storage of the thermostats. operative temperature.
The instrument is also equipped with an acquisition card having two adjustable inputs
(Pt100 3/4 wires; thermocouples: J, K, N, R, S) with bushes fitted with gold-plated contacts
and automatic compensation of the cold junction.
The first input is provided for the reference sample probe, thus obtaining a complete
calibration system which can be certified by SIT centres, in compliance with ISO 9000
regulations.
The second input is provided for probes that are being tested; hence, the instrument
can display the temperatures of the furnaces, the temperature of the sensor to be
checked and of the reference sample probe, at the same time.
Furthermore, TB300M is equipped with the RS232 serial interface; it can operate in
automatic mode connected to the PC by means of the AQ2SP software which enables
to carry out probe calibrations and cyclical life tests; test results can be stored and
printed, so they are easily traceable in compliance with ISO 9000 standards.
The TB300 M with the software AQ2sp for Windows can carry out:
- complete control of the bath from the PC,
- manual or automatic calibration of one or more probes,
- cyclic life or stress tests on temperature sensors,
- automatic threshold thermostat test,
- filing and printing of the results obtained, guaranteeing ISO 9000 standards
FLUID LEVEL ADAPTER ( by request )
The fluid level adapter slides directly into the test wells of the TB300 M bath is designed
for customers that needing to calibrate glass thermometers.
The fluid level adapter creates a positive bath fluid surface. The bath fluid is pumped up
through the test well to the surface of the bath and kept there. In relation to the liquid
viscosity the operator can regulate the level rotating the adapter tube.
The clear adapter cover protects the bath fluid from ambient temperature effects for
better bath stability. The cover can be drilled for any size probe.
CERTIFICATION
All the instrument are supplied with final testing, stability
and accuracy certification traceable to standards
