The TP-2 of the early 1980s
became a long time favorite of many petroleum inspectors. It was the first
portable electronic thermometer, PET, to challenge the long reign of the cup
case thermometer. Although the TP-2 was severely dated by 1990, many
inspectors wanted nothing else despite newer models by ThermoProbe and
various competitors. Because the US market demanded the return of the
venerable black box, ThermoProbe has put its newest circuit and software
design into the old familiar form.
The TP-2C employs the proven
RTD design that has been used in the TP-7 and TP-8 for many years. Where old
mechanical switches were vulnerable to damage and liquid penetration, a
sealed industrial quality overlay now provides a user interface that is easy
to use with gloves. A sealed, heavy gauge powder coated aluminum enclosure
replaces the vulnerable plastic case and protects the circuit board and
large LCD from penetration by impact, water and reactive liquids.
The new TP-2C circuit board
is an evolutionary step up from our highly accurate, reliable and successful
TL-1 laboratory thermometer. The Power Button's primary function powers the
instrument for intervals of about 20 minutes since the last button was
accessed. The Power Button can also be used to conserve power and clear the
memory, or to make adjustment while in calibration mode. A simple menu
operation is displayed by holding the Function Button f , and alternately
functions to allow adjustments in the calibration mode. Arrows on the left
side of the display show the direction of the temperature reading and
whether stability has been reached. At the user's discretion stabilized
temperatures can be logged at numerous liquid levels for a running average
and later displayed for the user's documenting purposes. But this feature
never interferes with simply getting an accurate temperature reading.
To endure the environment
and be intrinsically safe, the TP-2C is manufactured of materials, which are
both immune to petrochemicals and are non-sparking. The enclosure is made of
aluminum with a thickness of 0.080 inches. As with all ThermoProbe
instruments, the probe assembly is constructed with a very flexible,
static-dissipating, non-stick cable, and stainless steel sensor components.
OPERATIONAL ATTRIBUTES
Easily replaceable AAA
Batteries, provides an estimated 100 hours operation. Circuit logic
automatically indicates low battery condition, automatically shuts off after
twenty minutes, shows temperature trend and stabilization, displays error
codes for failure determination. The low power backlight for night operation
is photo sensor controlled for convenience and battery conservation. In
nighttime conditions the backlight illuminates the display for 5 seconds if
a button is pressed once, and then the buttons function in their usual way.
Celsius or Fahrenheit units with C/F indication can be easily chosen from
the Function Button. User Manual explains intuitive calibration procedure
that can be done through the external faceplate buttons.
