According to Hanna Instruments , HI 98801 and HI 98804 thermometers combine the high accuracy and fast response time of the printing series with an extensive logging feature and infrared computer transfer system.
These meters support K, J or T-thermocouple probes, one for HI 98801 and up to 4 for HI 98804. All stored data are always complete with date, time, sample and probe number. Measurements can be stored automatically at defined intervals (user-selectable from 1 to 180 minutes), or the current reading can be printed or logged-on-demand by just pressing a button. The backlit LCD allows operations even in poorly lit areas. Computer connection is through the HI 9200 infrared interface and serial port. Just place the meter on the interface and the HI 92000 application software will transfer all logged data. Both models can be powered with batteries or 12 Vdc input. Hanna produces a wide range of K-type thermocouple probes that can be used with this thermometer for many applications (HI 766 series).
HI 98801 is supplied with 5 paper rolls, batteries, rugged carrying case and instructions. HI 98804 is supplied with 5 paper rolls, batteries, rugged carrying case and instructions.
