## Overview

Delmhorst GB-1 Gypsum Sensor Blocks are precision-crafted soil moisture sensors featuring gypsum cast around dual stainless steel electrodes.

Easy to install and battery-free, they are trusted by professionals for extensive soil moisture monitoring.

## Description

From the Manufacturer Sensor blocks are made of gypsum cast around two concentric stainless steel electrodes. They are manufactured under controlled conditions to obtain a maximum degree of uniformity and fast reponse to soil moisture changes. It is the most widely used sensing unit, easy to install and especially suited for extensive sampling of soil at various depths. Gypsum blocks work best in soil types with a water holding capacity of 1.2 in/ft or more (clay to sandy loam)

Review: For the gardener who irrigates - Most moisture sensors measure conductivity, and are six inches to a foot or so in length. These are inexpensive well made gypsum blocks that measure soil moisture at any depth from a few inches down to four feet. You bury the block leaving the wire exposed. The blocks have a resistance of several hundred megohms when dry, and a few hundred kilohms when wet. The company makes a rugged field grade meter, or you can make/buy one if you are electonically savvy. These are great little items.
