## Overview

The Arduino® Thermocouple Multiplexer Shield (K - MAX31855K) enables multiple high-temperature readings with an Arduino board, supporting a wide temperature range from below 0°C up to 1200°C. Featuring screw terminals for secure thermocouple connections and pre-soldered headers for easy integration, it offers higher accuracy and resolution than previous models. Ideal for automotive, industrial, and scientific applications requiring precise 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.

Review: Wrong sized pin headers. - 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.

### ⭐⭐ Wrong sized pin headers.

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.
