  • Direct-to-USB connection and easy-to-use functionality
  • User-programmable alarm thresholds
  • All data loggers come with software
This selection of USB data loggers measures and records a variety of parameters including temperature, humidity, voltage, current, and carbon monoxide. Simply insert any of these compact, 4.5" (11.4 cm) L loggers into your computer USB port, name it, choose your required sampling rate, select high and low alarms if required, and set the logger start time. Once configured, the logger can be removed from the computer to log independently. Data is downloaded back onto the PC where it can be analyzed and viewed as a graph using included software.

Temperature. The low-cost model 23039-51 stores over 4000 readings and has a fixed 30-minute sampling rate and a measurement range of 14 to 122°F (–10 to 50°C). For ambient temperature measurements between –31 to 176°F (–35 to 80°C), model 23039-50 stores over 16,000 readings. For application requiring an extended temperature range, model 23039-66 measures from –40 to 257°F (–40 to 125°C), stores over 32,000 readings, and features a stainless steel enclosure for more hostile environments.

Temperature, Thermocouple. Models 23039-60 and -64 accept type J, K, and T thermocouples via a connector in the base of the unit and are supplied with one type K thermocouple rated from 32 to 752°F (0 to 400°C). These loggers store more than 32,000 readings. Model 23039-64 offers the additional feature of a 4-digit LCD.

Temperature/Humidity. These data loggers measure temperature and humidity from 31 to 176°F (–35 to 80°C) and 0 to 100% RH, calculate dew point, and store over 16,000 readings per parameter. Models 23039-65 and -67 offer increased accuracy. Models 23039-62 and -65 feature a 21⁄2-digit LCD showing latest log and min/max log and have immediate, delayed, and push-to-start logging.

Real-Time Temperature/Humidity. Model 23039-59 stays permanently connected to your computer USB port—displaying real-time ambient temperature, humidity, and calculated dew point on the PC monitor. Ideal for server room applications, this data logger can be programmed to send an e-mail or text message when a user-selectable alarm has been reached.

Process. Model 23039-54 has a 0 to 30 VDC measurement range and stores over 32,000 readings. Current measurement is provided by model 23039-56 which stores over 32,000 readings covering the 4 to 20 mA measurement range. Both units can be connected to external sensors via screw terminals located in their caps.

Carbon Monoxide. Use model 23039-58 for a 0 to 1000 ppm range and model 23039-68 for a 0 to 300 ppm measurement range; both store more than 32,000 readings. An bright red LED will flash and an audible alarm will sound when the user-determined level is exceeded.

    • Q:

      Can this product be used in a liquid nitrogen vapor phase (-196 C) environment?
      Asked on 7/16/2009 by Anonymous

      1 answer



        The datalogger unit itself can not be used in that environment. The range of the unit is -10 to 40 degrees C. The probe that comes with this unit is only rated for 0 to 110 degrees C. However, a different Type J,K,or T type thermocouple probe (with a mini-connector end) can be used to measure temperatures that low.

      It is so very easy to use and now I can concentrate on my work rather than having to learn how to use a new product. Data analysis is easy too!
