Supported Applications
The Omega HH378 Series is a four-channel handheld data logger thermometer designed for temperature measurement using Type J, K, E, and T thermocouples. The instrument features isolated input protection and includes Windows software for data processing via USB interface.
- Type J, K, E, and T thermocouple measurements
- Four simultaneous channel monitoring with 16,000 record storage capacity per channel
Operating Conditions & Performance
The HH378 Series operates within an ambient temperature range of -10 to 50°C (14 to 122°F) and a humidity range of 10 to 90% RH (no condensing). Storage conditions are specified as -40 to 60°C (-40 to 140°F) with 10 to 75% RH. Accuracy is defined as ±(0.1% of reading + 0.7°C) or ±(0.1% of reading + 1.4°F). For measurements below -100°C (-148°F), accuracy shifts to ±(0.4% of reading + 0.7°C) or ±(0.4% of reading + 1.4°F).
- Resolution: 0.1°C/°F for readings <1000, and 1°C/°F for readings ≥1000
- Sample rate: 1 time per second
- Battery lifetime: Approximately 30 hours (alkaline battery)
Configuration Options
The series supports four thermocouple types with the following measurement ranges:
- Type K: -200 to 1372°C (-328 to 2501°F)
- Type J: -150 to 1000°C (-238 to 1832°F)
- Type E: -150 to 750°C (-238 to 1382°F)
- Type T: -180 to 400°C (-292 to 752°F)
Power is supplied by a 9V battery (included) or an optional AC/DC adapter providing 9 Vdc (8-10 Vdc maximum). The unit features a USB interface for data transfer and includes Windows software. Standard accessories include four free 1 m Type K insulated beaded wire thermocouples with subminiature connectors, a hard carrying case, operator's manual, NIST certificate, and USB cable.
Key Product Differences
The HH378 model is the primary configuration in this series. Optional accessories include Model No. HH300-ADAPTER (Power adapter 115 Vac) and Model No. HH300A-CABLE-USB (Spare USB interface cable). The instrument dimensions are listed as 196 H x 65 W x 36 mm D (7.72 x 2.56 x 1.42") with a weight of approximately 310 g (10.93 oz).
