Temperature Data Loggers

MadgeTech manufactures a wide variety of temperature data loggers in the U.S.A. No matter where you are on the globe or what industry you represent, MadgeTech is the source for precise, reliable data measuring and recording. Our online catalog contains a wide variety of specialized, high-quality devices, including ultra-low-temperature (cryo), high-temperature, wireless, RTD (resistance temperature detector) and thermo couple data loggers.

Any MadgeTech data logger you choose for your temperature mapping and monitoring application will be a quality device whose construction bears the mark of MadgeTech’s state-of-the-art craftsmanship.

Temp101A Data Logger

The Temp101A is second to none in the compact, portable and low cost data logger class. This device can measure and record ambient temperature from -40 °C to 80 °C and is approximately the size of a matchbox which allows for easy placement even in tight spaces.


The HiTemp140 is a rugged, high precision, temperature data logger that is built for use with autoclaves and harsh environments. This stainless steel device is submersible, can withstand temperatures up to 140°C (284°F) and has an accuracy of +/-0.1°C (0.18°F).

EggTemp data logger

MadgeTech’s EggTemp data logger is specifically designed to measure and record data of the temperature of eggs during shipping, storage and incubation. The data logger thermally responds to an environment the same way a real egg does, simulating the temperature experience of the actual product.

Introducing the LyoTemp Data Logger, designed for use in ultra-low operating temperatures for processes such as Lyophilization. The LyoTemp has an operating range of -60 °C to 75 °C, and is designed with a hermetically sealed thermistor temperature sensing element in a long thin flexible cable form, making it ideal for monitoring products during the lyophilization process.
Cryo-Temp Data Logger
Ultra low temperature data logger, records temperatures as low as -86°C. The Cryo-Temp can be used in a broad line of applications such as monitoring blood plasma, vaccines, pharmaceuticals, frozen foods and shipping containers. This stand-alone device does not require any additional probes. The enclosure is designed with a handle for easy attachment and is splash proof. It utilizes a USB docking station to communicate with a personal computer (USB docking station sold separately).
OctTemp Data Logger
The OctTemp2000 is an eight channel thermocouple temperature data logger with an LCD. The device features onscreen minimum, maximum and average statistics, as well as a user configurable graphics screen that allows for any combination of channels to be displayed. The device accepts J, K, T, E, R, S, B and N type thermocouples. (Also available in 4 Channel)
IRTC101A IR Data logger
The IRTC101A is a battery powered infrared thermocouple based temperature data logger. It provides nearly instantaneous, non-contact temperature measurements, making it a perfect solution for applications such as surface temperature recording and monitoring moving objects. The IRTC101A features a 10 year battery life, 1 second reading rate, a multiple start/stop function, ultra-high speed download capability, 500,000 reading storage capacity, optional memory wrap, battery life indicator, optional password protection, programmable high-low alarms and more.
The TransiTempII is a low cost, splash proof temperature data logger featuring a highly precise semiconductor temperature sensor and an ABS plastic enclosure. This affordable device is ideal for monitoring and recording the temperature of all types of perishable products, including food items and medical/pharmaceutical goods, both in storage and in transit.
The TCTemp2000 is a thermocouple temperature data logger perfect for applications requiring instant remote readings of temperature. The 8-button keypad and large LCD provide convenient access to current data and data logger setup. This data logger has an internal temperature sensor and one external input for J, K, T, E, R, S, B and N type thermocouples.
