## Overview

The WATER MARK Irrometer Model SR, 18" is a professional-grade soil moisture gauge designed for irrigated crops, greenhouses, and nurseries. Featuring a durable, chemical-resistant Butyrate plastic body, a quick-response replaceable ceramic tip, and a hermetically sealed gauge measuring 0-100 centibars/kPa, it delivers precise soil suction readings. Its large water reservoir and leakproof design ensure easy maintenance and reliable performance, making it an essential tool for efficient water management.

## Description

The Model SR is the standard Irrometer for general use with irrigated row, tree, and field crops, but can also be used in greenhouse and nursery applications or for monitoring Vadoze Zones. Features a tough Butyrate plastic body that is impervious to soil chemicals or electrolysis, a replaceable porous ceramic tip designed to give quick response to variations in soil moisture, and a hermetically sealed gauge that indicates soil suction from 0 to 100 centibars or kilopascals (gauge operates counter-clockwise). The replaceable ceramic tip is easy to service in the field and is much stronger than conventional tips. A large reservoir with a screw cap for filling holds a reserve supply of water to replace water lost by the action of drying soil. Partial unscrewing of the cap releases air and refills the tube from the reservoir. All ceramic-to-plastic connections are guaranteed leakproof. Irrometer fluid, supplied with the Service Unit accessory, adds color to the water for easy water level observation. The Model SR Irrometer requires the Service Unit accessory and the Soil Coring Tool with the initial order.
