DE-305
Thermocouple Thermometer

Our full-featured DE-305 is a breakthrough for the entire field of temperature probe measurement.

Using the popular K type thermocouple, this new instrument breaks price barriers and maintains all of the performance characteristics of more expensive instruments.

The MAX button is useful for cold room monitoring. Just hit the MAX button and the unit will tell you the maximum temperature sensed since the button was pushed. Any type of K thermocouple probe can be used with the instrument. A wide range of specialized probes are available for virtually every temperature monitoring application for food processing, storage or retail. The unit is supplied with a convenient "flip out" table stand. The temperature HOLD function is useful to "freeze" a particular reading on the display for later recording.

AquaTuff Thermocouple Thermometer  



This thermometer was originally designed for a well known fast food chain and was specifically made to conform to their exacting standards for durability, precision and ease of use.

Now, with the new AquaTuff designation, the quality has gone even higher.

The unit is highly durable and is completely waterproof. The body unit is high impact ABS plastic.  The operating buttons and face of the unit are sealed with a thick and durable membrane panel for ease of cleaning.  The whole unit is secure for substantial impact resistance and use in wet and dirty environments.  

AquaTuff not only is fully waterproof, it is highly accurate, convenient to use, and about as rugged as you can get in a precision instrument. Over the years, nothing else has come close.  This latest in thermocouple design, the AquaTuff is the result of years of design refinement based on field experience. 

The unit is also easy to hold, as the extrusion body has ergonomically designed ribs for a good grip.  Response is rapid and steady.   This is a very high quality instrument that will last for years and years of heavy industrial use.

Operating Range: +32F to +122F (0 to +50C)

AquaTuff High Accuracy with Integral Wrap Cord Probe
This is truly a legendary series of instruments.  Starting with the AquaTuff features, these instruments achieve a higher level of accuracy by compensating for an integral probe...each unit is individually pre-calibrated.

The unit is designed to allow the probe handle to "snap in" to the case (as shown at right) when stored.  Cord wraps around the body of the unit in a specially designed retainer groove.

Global Sensors has the best pricing anywhere on this remarkable tool. The AquaTuff series as created to answer to the need for a very high accuracy thermocouple thermometer that can also withstand substantial abuse, including immersion.  No other instrument even comes close to the unique combination of characteristics of this product line.  Higher accuracy is achieved by using an matched probe (use only a Global Sensors replacement probe) that is calibrated specifically with the thermometer response.

Operation is simple with only two buttons on the control surface. 
Wind cord around perimeter of unit, pulling cord tight.
Snap probe handle into slot at upper right corner.
Unit is ready for convenient storage.

NEW Super Accurate Digital Thermometer
 


This remarkable digital thermometer is actually not based on thermocouple technology.  It uses high accuracy RTD sensor probes that are fitted individually to the base unit.  Each unit is certificated to ISO certified lab standards and documentation of NIST traceability is provided.

This is the unit you would use to perform all calibration checks necessary in an operation.  If you have this unit, you do not have to send your temperature measuring units out for lab certification.  As long as your own certificate is no older than one year, you are operating on the same basis as a certified lab.

Temperatures are reported to three decimal places for both C and F readings.
An option that is provided with this unit is the capability to operate it as a temperature logger.  Call us to ask about the pricing and availability of the logging kit.  The port in the side of the unit is designed to connect to a PC computer serial port and send logged temperature data to a spreadsheet.

The cable and software logging kit is a separate purchase and is NOT included with the unit as priced here.  Call us for pricing and availability.
Almost instantaneous response time with the RTD probe of this unit.

You must select the type of probe to be matched to your unit.  There are three options currently available.  The Needle Tip is standard order, the Surface Probe and Air Probe must be special ordered.

High Accuracy Platinum RTD Thermometer

Not quite at the same level of accuracy of the Super Accurate (above) but quite capable of serving as a reference standard for a multiple thermometer operation. 

Or, if a rugged unit is needed that provides higher than normal accuracy, this is the unit.  This model has been around for a long time, and users who are familiar with its unique combination of accuracy and durability keep coming back for more units.

The unit has the same wrap cord stowage feature as the AquaTuff units (see illustration above).

You have to try hard to break this cable. This custom fabricated cable is designed for toughest food usage. On the inside are the insulated Copper conductors, followed by a sheath of Kevlar high tensile-strength strands, then an outer layer of Teflon, next a woven metal shielding, then finally a silicone jacket in an FDA-approved food safe formula.  The entry into the probe handle is steel protected and molded in.

0.5F from -76.0F to 199.9F & 1F from 200F to 500F  
Durable inner-woven-metal cable withstands 500F heat and 50 lb pull
Covered switches and housing
O-Ring sealed for water resistance.
