We are pleased to announce the NEW
Wahl DST600 Digi-Stem® Digital RTD Thermometer
for Low-Acid Canned Food Retorts, Dairy Processors, USDA, Pharmaceutical Companies and Temperature Critical Applications

SPOTLIGHT ON... 

The Wahl® DST600 is the new standard against which all other
temperature indicating devices are compared.

Key Features and Benefits

  • Exclusive Patent-Pending Wahl® Continuous Self-Checking Technology to ensure accuracy and reliability
  • Trustworthy Alternative to Mercury-in-Glass
  • Exclusive Adjustable Meter Update Rate
  • User Selectable °F or °C
  • Ambient operation at -40°F  to 158°F
  • Unique Probe ID Feature prevents use of un authorized probes
  • Long Battery Life - 2 year nominal
  • Adjustable Angle, Rigid, or Remote configurations available
  • Programmable "R?" for "matching" sensor to meter
  • User friendly Single Point Software Calibration
  • Tamper Resistant- all adjustments require software
  • Exclusive Quick Disconnect Connection option on Remote Cables
  • NIST Traceable Certificate of Calibration included

Innovative New Technology
Mercury-in-Glass (MIG) thermometers, the only standard for years, can now be replaced with other technologies under the FDA proposed rule change. Wahl's NEW! DST600 is a patent-pending, dependable, digital RTD Thermometer System which offers new technology designed specifically to meet the FDA Proposed Rule change for 21 CFR Part 113. This rule mandates that a temperature indicating device provides permanent accuracy, no drift over time, and reliability for processors of low-acid canned foods under actual plant operating conditions. It also meets current USDA 9CFR318.300 for canned meat and 9CFR381.300 for canned poultry products.

Continuous Self Checking Accuracy
The Wahl DST600 meets and exceeds the FDA rules by incorporating patent-pending self-checking technology which continuously verifies the accuracy of the electronics, and indicates any out-of-tolerance conditions, assuring that its accuracy and ability to function properly during processing are not compromised. Test temperatures are set at 180°F (82°C) and 250°F (121.1°). Out-of-tolerance conditions will be displayed as an error, and immediately indicate to the operator if accuracy is not maintained, preventing under- or over-processing of product.

 

Wahl DST600 Adjustable Angle
mounting system allows meter adjustment to any angle required for best viewing.

Drop-in Direct MIG Replacement
The Wahl DST600 offers the highest precision temperature measurement technology with many unique features - making it the best choice for your processing needs. It has a field replaceable battery with a 2 year life, and provides a trustworthy alternative to MIG style thermometers with drop-in direct replacement. It is available with MIG standard tapered bulb chambers, 1" high LCD display - readable from 30 feet away!

Optional Quick Disconnect for Calibration Convenience
Optional Quick Disconnect for both probe and meter connections offer convenient calibration. This industry leading, and time saving capability allows the probe and meter to be removed and taken to the calibration lab and calibrated as a system - without removing the permanent installed cable.

Probe ID and Probe R?

Probe ID
- The Unique Probe ID feature verifies that the authorized probe is connected to the meter. If an unauthorized probe is connected, the meter will display "Prb", indicating the need to perform the probe authorization and probe calibration functions. Probe ID is available on Adjustable Angle, Rigid, and Remote probes up to 30-meter lengths.

NO OTHER SYSTEM HAS THIS SAFETY FEATURE!

Probe R? -
The Wahl DST600 includes an exclusive compensation feature utilizing a programmable R? calibration coefficient for increased accuracy. This allows the meter and probe to be "matched" to each other, and along with the Probe ID feature, guarantees an accurate and secure system.

DST600 Programming Software

DSTPROG Programming Software Kit -
This Software allows the customer to configure the following parameters:

  • Sample/Display Rate - Factor default at 1/second. Adjustable from .25 seconds to 10 seconds in .25 second intervals. Slower update rates extend battery life.
  • Probe R? - Compensation feature which allows calibration of meter to be "matched" to probe.
  • Probe Authorization - Allows user to change probes and authorize a new probe with the existing meter.

Wahl DSTPROG and DSTCAL Software Kits are user friendly and include on-screen prompts for guiding the user through their operation. Both kits require Windows XP to operate, and includes a USB cable, USB to Computer Interface Box, and Digi-Stem Serial Interface Cable in order to connect the Wahl DST600 to PC.

DST600 Calibration Software

DSTCAL Calibration Software Kit -
This exclusive software allows setting of the same configuration parameters as DSTPROG, but also allows the following calibrations:

  • Meter Calibration - uses an ohmmeter to calibrate the resistance measurement electronics by connecting to known fixed resist
  • System Calibration - used to calibrate a sensor to a meter using a standard ice bath.

Software Accessories

DST600 Fixed Probe Calibration Cable Assembly - 13500-3
Extends the probe leads when performing system calibrations on fixed probe systems. Allows the meter to be conveniently placed on the benchtop, while the probe is installed in an Ice bath.

DST600 Interconnect Calibration Cable - When probe wiring is difficult to remove, simply disconnect the probe and meter from the cable, and use the 2 meter interconnect cable for performing lab calibration. Determine appropriate model number below, based on length of installed cable.
12370-002 - 6 Conductor, for cables less than 30 meters.
12360-002 - 4 Conductor, for cables greater than 30 meters.
