Accurate temperature measurement is essential for maintaining product quality, process efficiency, regulatory compliance and operational safety in industrial processes. High performance, stable temperature sources are the solution for achieving optimal performance of temperature sensors and process instrumentation, by providing reference temperatures for checking and calibrating these devices. The Druck Dry Block and Liquid Bath Temperature Calibrators provide solutions for testing temperature devices over a range of temperatures from -35°C to 650°C (-30°F to 1200°F) with a choice of dry block and liquid bath configurations to accommodate virtually any type, shape and size of sensor.

The design philosophy is one of simplification, that is, simplifying the complex arts and skills of temperature calibration to provide instrument technicians with a highly accurate, yet simple to use temperature reference.

Features:

• Calibrated to EA-10/13 (European Co-operation for Accreditation Guidelines on the Calibration of Dry Block Calibrators) ensuring high accuracy without the necessity of a reference probe!
• Quick and easy touch screen setting and set point memory recall
• Dry block and liquid bath configurations with multi use options for switching between dry, liquid and infra-red well inserts
• Accommodates anything from unique probe sizes to irregular shapes and provides a massive 60mm x 170mm capacity for simultaneously testing multiple sensors

These dry block calibrators incorporate the latest metal block and electronic control technology and offer a choice of precision bored well inserts to accommodate a wide range of test devices. Two models are available:

• DryTC 165 generates temperatures from Room Temperature (RT) to 165°C
• DryTC 650 generates temperatures from ambient to 650°C.

Both models provide high accuracy, excellent set point stability and rapid heating and cooling times.

• Temperature range from Room Temperature (RT to 650°C)
• Accuracy from ±0.2°C
• Stability 0.05°C
• Rapid heating and cooling
• Light weight and robust for field use
• Choice of interchangeable well inserts
• Easy to set-up and use

Dry well insertion sleeves
Dry block calibrators greatly simplify the test and calibration of process sensor heads, probes, switches and thermometers, but optimum performance relies on a good fit of the device in the well insert. To facilitate this, a range of insertion sleeves are available with hole diameters to suit the most common probes and devices.

These multi-purpose calibrators combine the portability of dry block calibrators with the flexibility of liquid immersion baths to enable the testing and calibration of virtually any shape and size of devices. The calibrators can be reconfigured by the user to function as a liquid bath, as an infrared black body source and as a dry block calibrator with interchangeable inserts. The latest heating and electronic control technology, combined with continuous liquid agitation of the fluid bath, provide high accuracy and stability throughout the large homogeneous measuring zone. The calibrators are factory configured as liquid baths and are provided with a bath cover to hold up to 5 devices while reducing heat loss from the surface of the liquid medium. For transportation a leak-proof sealing cover is also provided as standard. Optionally the temperature calibrators can be configured with additional capabilities including interchangeable liquid baths, a black body source and dry block interchangeable inserts. Two models are available:

• LiquidTC 165 generates temperatures from Room Temperature (RT) to 165°C
• LiquidTC 255 generates temperatures from ambient to 255°C
• Temperature range from Room Temperature (RT to 255°C)
• Accuracy from ±0.2°C
• Stability 0.05°C
• Large bath for irregular and multiple devices
• Multi-purpose – liquid bath, black body source, dry block
• Interchangeable bath – simplifies fluid changes
• Light weight and robust for field use
• Leak-proof bath cover for transportation

High capacity portable liquid bath
Standard factory configuration provides a 60 mm x 170 mm liquid bath with automatic liquid agitation.
Interchangeable liquid bath inserts
Allows the calibration media to be simply and quickly changed to suit different temperature ranges, while retaining the automatic liquid agitation.
Infra-red black body source
A specially constructed insertion sleeve provides an emissivity of 1 (black body).
Dry well insertion sleeves
For the convenience of a dry block calibrator a range of insertion sleeves are available with hole diameters to suit most common probes and devices.

Controller OFF – disables automatic temperature control at the last set point temperature to allow the calibrator settings to be changed part way through a test.
Manual control – allows the power output of the calibrator to be adjusted to control the rate at which the calibrator reaches the set-point temperature.
Set-point memory – allows up to four set-point temperatures to be stored in memory. The test sequence can then be activated with a single key press.
Test profile – this function defines a temperature profile with a heating rate to the first set-point value, a test duration or soak time at set-point one followed by a cooling rate to a second set-point.
PC communications -An optional USB cable is available for connection to a PC.
