Cooper Instrument Corporation Electro-Therm SH66A multi-probe digital temperature tester with its fitted hard carrying case, temperature probe accessories and original cardboard box as pictured. This is a professional-style three-channel temperature instrument for measuring individual probe temperatures and differences between readings.
The SH66A has an LCD readout and membrane keypad with ON, OFF, °F/°C, TEMP DIFF, individual TEMP 1, TEMP 2 and TEMP 3 selection buttons, and a LIGHT button. The original box specifies a temperature range of -40°F to 300°F (-40°C to 150°C), 9-volt battery operation and a shock-resistant carrying case. The case contains an operating-instructions label inside the lid.
Included are the digital meter, the visible coiled wired probe and additional cable/probe accessories, fitted carrying case and original Cooper retail cardboard box. The exact accessories included are shown in the photographs; please inspect them for the types of probes and connectors.
TESTING: The unit was powered on and the LCD illuminated, displaying "LO" with TEMP 1 indicated, as photographed. According to the SH66A operating instructions, "LO" is the normal display when no probe is connected to the T1 input. No temperature measurement or probe accuracy testing has been performed. No testing of the other channels, calibration, or extended operation has been done. Functionality beyond power-on is unknown.
Cosmetically, the meter and hard case show age-related handling marks, surface dust and light wear. The original cardboard box is heavily worn, with creasing, scuffs, tape wear, torn edges and flaps, and discoloration. The case interior and its instruction label are shown in the photos. Please review the pictures for exact cosmetic condition and contents.
Sold as a pre-owned, power-on-tested instrument with no guarantee of probe function or measurement accuracy. You will receive the actual meter, accessories, carrying case and original box shown.

Seller DisclaimerI do my best to photograph and describe every item as accurately as possible. Please review all photos carefully, as they are considered part of the description and show the exact item you will receive.
Items are not fully inspected, tested, or disassembled unless specifically stated in the listing. Any accessories, parts, components, manuals, packaging, or other contents included with the purchase are limited to what is shown in the photos and described in the listing.
Condition can be subjective, especially with vintage, antique, used, and pre-owned items. Normal age, storage wear, surface marks, discoloration, dust, scratches, oxidation, or other signs of previous use may be present. Please zoom in and review all photos carefully to make sure the item meets your expectations before purchasing.

I make every effort to keep shipping costs as low as possible. The shipping amount charged to the buyer is intended to cover the actual carrier postage cost only. I do not add charges for boxes, tape, bubble wrap, labels, or other packing materials, and I do not make a profit on shipping. Those packing costs are absorbed by me.
Once a package has been accepted by the carrier, transit times are outside my control. Delays can occur during holidays, peak shipping periods, severe weather, and other high-volume times.
Carrier-provided delivery estimates are estimates and may change after shipment.
