Product overview: 7009/7108/7015 Resistor Baths
7015
The 7015 has a 95-liter tank and a temperature range of 0 °C to 50 °C. It’s stable to ±0.0007 °C.
It has a one-piece stainless steel lid designed to drain spills and splashes back into the bath as you remove resistors. It has a large access opening to make handling large resistors, like the Thomas design standard resistors, easier. The tank has an electrically isolated resistor shelf.
This is truly a quality resistor bath, and it’s backed by our industry-leading service.
7009
This is a large bath with a tank 27½ inches long by 22 inches wide. It has a temperature range of 0 °C to 50 °C and a stability of ±0.0007 °C.
For a bath this size and with these specs, it is priced extremely well. The Model 7009’s large tank can handle many resistors of any size.
7108
This is the quietest resistor bath you’ve ever heard. The 7108 uses thermoelectric (Peltier) modules to provide heating and cooling over its range from 20 °C to 30 °C. Without a compressor, noise is dramatically reduced. Power requirements are also lower, so you save money running the bath and add less heat load to your lab.
With a 51-liter (13.2-gal) tank, the 7108 holds plenty of resistors. A large 14" x 14" (356 x 356 mm) access opening allows you to easily move resistors in and out of the bath. A resistor rack comes with each unit that fits across the bottom of the tank. Made from hard-anodized perforated aluminum, this rack maintains the necessary electrical isolation between your resistors.

| †Although the 7015 and 7009 baths are capable of reaching higher temperatures, they are designed for use with standard resistors. Therefore, the soft cutout of the instrument has been set at the factory to 50°C to protect standard resistors placed in the bath. | |||
