Quick Disconnect (Standard Size Connector) to Mini Connector Adapter, Model Q-K-AD This is a 10 inch long adapter from standard size, round pin, quick disconnect to miniature mini K-type thermocouple connector. Many industrial k-type thermocouples come with the standard quickconnect plug, while most handheld thermocouple thermometers come with the mini plus, which have two spade like flat blades. This makes it hard to read or test a temperature at the machine or in the filed. This adapter bridges that gap and allows you to connect the probe, such as out Quick Disconnect K-type Thermocouple Q-K-01, to a K-type thermometer. Note: Thermometer and probe in the last picture for illustration of use only, not included in the offer. You get only the adapter wire. This K-type thermocouple is made with K-type thermocouple wire and plugs made from compensating metal, chromel and alumel.
