Note: -TC, -RTD and -TH models come with 1m (40") of lead wire standard. For longer lead wire add suffix "-(#)FT"and add $1.00/ft (over 3') to price. For "-RTD" models, add $2.25/ft to the price.
Example: EWS-TC-K-8FT, wall mount Type K thermocouple sensor with 8' lead wire, $39 + 5 = $44.
Ordering Example: (1) EWS-TX Temperature Transmitter, EWS-MB, Bracket/Wall Plate, (1) PSR-24S Regulated Power Supply, (1) TX4-100 Transmitter Cable = $169
