The TL2-A is a versatile 2-channel precision bench top thermometer offering a convenient USB interface for data logging and sensor configuration. The TL2-A is two thermometers in one instrument, with two channels allowing simultaneous temperature measurement in different locations. The TL2-A is well suited for establishing temperature traceability in equipment that requires high accuracy. The TL2-A is also perfect for metrology applications and as a calibration reference thermometer.
The TL2-A can be ordered with sensors included or the user can provide their own sensors. Sensor coefficients can be entered from a PC making it easy to change from a daily use RTD to a SPRT including user selectable choice of ITS-90 or Callandar-Van Dusen equations. Units come with 5 point resistance calibration from 20 to 425 ohms. With available PRT(s) ThermoProbe can provide a temperature reference system. Standard sensors are 100Ω wire-wound platinum RTDs in a stainless steel ¼” sheath 13” long. The sensors are provided with a standard 5 foot cable and DIN plug. Custom configurations and temperature ranges are available upon request.
The intuitive user interface allows easy configuration of temperature units, display resolution and a relay output. Minimum, maximum and average temperatures are automatically stored to memory for later reference. The interface allows viewing of Highest, Lowest and Average Readings, Zero Offset adjustment for sensor drift and readings in C, F, K and Ohms. The versatile data logging feature can be used to send data to a PC or stored to a USB Flash drive.
The TL2-A is constructed from rugged powder-coated steel and aluminum. The large backlit display is easy to read from a distance. With the provided AC power supply, the TL2-A is ideal for bench top or laboratory applications. A one year warranty, calibration report, USB cable, Flash drive, interface software and country specific power adaptor are included.

This grouping of hydrometers are not ASTM – but are enormously popular in the same applications as the ASTM 21 through 39H hydrometers. All are 165mm in length, graduated in 0.2 API divisions, and made to the same demanding tolerances as ASTM hydrometers. Each hydrometer can be ordered with or without NIST Traceable Report of Test by adding or removing the "C" to the catalog number.
Approximately 190mm (7-1/2″) Length. Thermometer in body. Not ASTM designated, but made to similar specifications. Popular due to the smaller sample amount (approx. 6 ounces) ounces needed to obtain a reading. Made to the same demanding tolerances as ASTM hydrometers. Accuracy: +/- 1 scale division. Each hydrometer can be ordered with or without NIST Traceable Report of Test by adding or removing the "C" to the catalog number.
Eight hydrometers 500-231 thru 500-238 below, covering the range from .700 to 2.000 A thermometer range 0/230 °F is included. Supplied in a sturdy foam cushioned case with carrying handle. Each hydrometer can be ordered with or without NIST Traceable Report of Test by adding or removing the "C" to the catalog number.
.070° Specific Gravity ranges, 6″ length. Made to the same exacting standards as ASTM hydrometers, these units have found wide application due to their slightly longer, overlapping ranges. Accuracy to +/- .001 Specific Gravity. Each hydrometer can be ordered with or without NIST Traceable Report of Test by adding or removing the "C" to the catalog number.
.070° Specific Gravity ranges, 13″ length. Made to the same exacting standards as ASTM hydrometers, these units have found wide application due to their slightly longer, overlapping ranges. Accuracy to +/- .0005 Specific Gravity. Each hydrometer can be ordered with or without NIST Traceable Report of Test by adding or removing the "C" to the catalog number.
