DST700 Wahl Digi-Stem® Digital Thermometer

Digi-Stem Meters & Probes are sold separately and paired together to create a complete custom system. This listing is for the meter only.

Please review our Order Guide and choose the meter power source, mounting, and other specifications needed to build a meter.

Description

The DST700 Wahl Digi-Stem® Digital Thermometer with Data Logger is the next generation of our Wahl Digi-Stem® Digital Thermometers with advanced capabilities.  Advanced functionality includes a data logger to record up to 1 million temperature data points with time stamp.  Optional Transmitter and Switch can be added for a fully selectable advanced alarm system: High alarms show red backlight and screen icon, while Low alarms show a blue backlight and screen icon.  Normal readings display with a green backlight.

Continuous Self-Checking Technology consistently verifies the accuracy of 10 critical factors for the electronics and the sensor, and indicates any out-of-tolerance conditions with a unique error code.  This ensures that the accuracy and ability to function properly are not compromised during processing.

Use the Optional Switch for various relay actions and the Transmitter, for continuous, precise temperature measurement data.  User Selectable: 4-20mA or 0-5V DC.  This option requires user supplied 24V DC power.

The large 0.9 inch high LCD display is readable from 30 feet away, with user selectable display resolution, switchable between whole degree or tenths of a degree, F/C.

Our Digi-Stems® are known for their reliability and rugged cases.  The housing is stainless steel with a NEMA-4X, IP68 rating.  Polycarbonate H frame is standard.  Dimensions are 5.3 inches wide x 4.3 inches high x 2.7 inches deep (135 mm wide x 109 mm high x 69 mm deep).

Choose from rigid, remote, or adjustable angle RTD probes built to order to customer specification and sold separately.  The DST700 Series features Easy Connect connectors making it simple to securely connect or disconnect the meter without removing the installed probe. This enables plug and play compatibility between DST700 series remote probes.  Our RTD models have a wide temperature range and high accuracy design for applications that require accurate and reliable temperature monitoring.

Choose which battery type you prefer.  Standard is one C size, Lithium Thionyl Chloride, 3.6V battery.  Optional AA Lithium Thionyl Chloride, 3.6V battery can also be selected.  Due to shipping restrictions, meters are shipped without the battery installed.  (Purchase the required battery from a supplier near your location.)

The DST700 includes Wahl Data Logger software on a flash drive. This model is not compatible with DSTCAL software.

Digi-Stem® meters and probes are sold separately for a completely customizable system.
