Electronic Multifunction Data Loggers
The environmental condition of food, pharmaceuticals, chemicals, and other temperature-sensitive commodities must be carefully monitored and documented to ensure safety, quality and longer shelf life.
The DeltaTRAK Electronic Data Logger is a portable, pocket sized electronic device powered by a 10-year lithium battery. It is designed for easy and reliable tracking of parameters such as temperature, relative humidity, electric current, pressure, process signals, and pulse signals. All data loggers have a built-in temperature sensor plus single or multiple external channels where different sensors can be attached for remote monitoring of a variety of parameters. The DeltaTRAK Data Loggers interface with a PC and have an internal memory for up to 32,000 readings. Each data point is automatically time and date stamped as it is recorded. Sampling intervals are set by the operator via a user-friendly Windows program on the PC. Recorded data is downloaded and graphed or exported in ASCII format to a spreadsheet for numerical print outs.
Aside from a built-in temperature sensor, each model’s additional capabilities are as follows: The 20500 has one channel for remote temperature monitoring, while the 20508 has seven external temperature channels. The 20501 has an on-board RH sensor and two external channels for temperature, relative humidity or resistance. The 20502 has three external channels for electrical current probes. The 20503 has two channels for pulse signals and dry switch contact closures. The 20504 has an optional on-board RH sensor and three channels for pressure, temperature or a combination RH/temperature sensor. The 20506 has six channels for types J, K, S or T thermocouples. The 20507 has seven channels for analog voltage and current loop signals via commercially available transducers.
