HI 140 loggers are not much larger than a PC mouse. They are housed in a smooth, yet tough ABS casing that is sealed against ingress of dust and water. These dataloggers represent the most economical and secure way of monitoring temperature continuously over long periods of time. For instance, users can check if fresh fish remained at unacceptable temperatures and for how long. They can provide that extra guarantee that goods never ventured out of limits of public safety. A green LED on the front of the meter notifies users of the logging status, while a red LED serves as an alarm indication when undesired temperatures have been encountered. HI 140 can store up to 7600 measurements at selectable intervals from 1 minute to 24 hours. All parameters can be set throughWindows compatible software. An infrared cradle eliminates the need to put a connector on the meter - an undesirable dirt-trap in the food market and source of problems due to wear and tear over time. Logged data can be transferred to a PC by simply placing the instrument on the interface and running the software. Users need just one interface connected to the PC to handle all Hanna dataloggers, each identified by a unique ID code. The instruments are equipped with BEPS (Battery Error Prevention System) which alerts the user in the event that low battery power could adversely affect readings. All HI 140 models are supplied with batteries and instructions. All loggers have the following features: programmable high and low alarm thresholds; programmable logging interval from 1 minute to 23 hours and 59 minute; logging delay start selectable from 0 minute to 23 hours and 59 minute; programmable ID number; infrared communication with PC interface; programmable real time clock; 3 x 1.5V AA batteries (included) with approximate life of 4 years at 25 degree C; Measures 86.5mm diameter by 35mm height. Temperature datalogger with molded eye hook for easy mounting.
