Choosing the Right Digital Meters for AC and DC Measurements in Field Conditions

Digital meters used for AC and DC measurements in the field must be durable and equipped to handle harsh conditions. Standard indoor meters are limited to 10 megaohms and are unsuitable for outdoor use, especially in wet environments. In contrast, specialized field meters are waterproof, float when dropped in water, and can measure up to 200 megaohms, making them ideal for taking potentials in high-resistivity soils or under sand-bottomed tanks. These field meters are specifically designed for outdoor AC and DC work and are immune to sunlight, ensuring accurate readings in various environmental conditions.
