PTC Series (PTC125 / PTC155 / PTC350 / PTC425 / PTC660)
AMETEK continues to develop new techniques to improve performance, accuracy, convenience and functionality of the well-known JOFRA calibration products. By doing so, we maintain our position as the leading worldwide manufacturers of temperature dry-block calibrators.
The PTC series provides precision temperature calibration of sensors, whatever the type or format. This is accomplished through an innovative active dual zone heating technology where each heating zone is independently controlled for precision temperature calibration.
Features Informative Color Display and Easy Operation
The PTC’s full color VGA display is very easy to read. The main temperature indications, like SET, READ, TRUE and SUT (Sensor Under Test), are always displayed at all stages of the programming or calibration procedure.
The navigation is very logical to use and the display indicates all important information needed for the current function.
The PTC Series calibrators come in three different models:
• Model A - basic model, without input
• Model B - full model, with DLC sensor input and input for reference sensor and sensor-under-test
• Model C - middel model with DLC sensor input and input for reference sensor
The PTC-125 with both heating and cooling capabilities features the FPSC (Free piston stirling cooler) as the cooling source. It is much more efficient than thermo-electric (Peltier) coolers.
Models and Temperature Ranges:
PTC-125 from -90 to 125°C (-130 to 257°F)
PTC-155 from -25 to 155°C (-22 to 311°F)
PTC-350 from 33 to 350°C (91 to 662°F)
PTC-425 from 33 to 425°C (91 to 797°F)
PTC-660 from 33 to 660°C (91 to 1220°F)
