## Overview

The Arduino® Thermocouple Multiplexer Shield (K - MAX31855K) enables multiple high-temperature readings with an Arduino board, supporting a wider temperature range including below freezing, higher accuracy, and resolution. It features screw terminals for secure thermocouple connections and is powered via a 3.3V Arduino pin, compatible with 5V systems. Ideal for automotive, industrial, and scientific applications requiring reliable multi-zone temperature monitoring.

## Description

Note: This version comes with headers pre-soldered to the board. Please allow 24 hours for shipment.  Description:  The KTA-259v5 Thermocouple Multiplexer Shield is designed to easily allow multiple high temperature readings with an Arduino control board.  With the new version there are multiple advantages over the old KTA-259, namely, wider temperature range including below 0°C, higher accuracy, higher resolution and ability to use more thermocouple types (dependent on model).  Screw terminals are provided for thermocouple connections as thermocouple wires can not be soldered.  Uses:  Automotive – Engine, Exhaust and Brake temperatures are higher than most temperature sensors can handle, but within the range of Thermocouples.  Ovens, Furnaces and Kilns – At temperatures where other temperature sensors will not operate.  Freezer or Cryogenic monitoring – Where temperatures are well below 0°C.  Chemical Processes – Where corrosive chemicals may damage probes or reach high temperatures thermocouples are more readily available for such processes.  Multi-Zone Temperature Monitoring, Data Acquisition or Logging Systems– With cheap readily available thermocouples.[1] This is the range of temperatures that a thermocouple of this type can measure, the Measured Temperature Range is the actual range the KTA-259 can digitize.[2] KTA-259 and KTB-259 are discontinued and are included for reference only.

## Customer Reviews

### ⭐⭐ Wrong sized pin headers.
*by A***E on February 16, 2024*

The picture on the left show they used a short header so it is missing the two I2C pins and ones for the extra 5V and GND on the other side. On the right is a board I got directly from Ocean Controls with the correct length headers.
