Colorado Portable Meters

Portable meters made easy to use with dependable results in field or laboratory environments. Colorado Portable Meters offer accurate measurements anytime, anywhere.

Grab and Go. Ergonomically designed to fit either hand. Compact and lightweight for travel. Durable housing withstands the rigors of field use. IP-65 rating for complete protection from dust and water projection.

Straightforward Functionality. Simple four key operation. Large display clearly shows measurement. Simultaneously, displays the measurement value and temperature reading (with optional ATC). Basic single press calibration routine. Battery icon indicates battery life. Buttons emit audio feedback.

Dependable measurements. Easy 1-2-3 standardization for the most accurate measurements. Automatic standards recognition and electrode efficiency check. Automatic temperature compensation with optional ATC or temperature can be set manually. Stability icon for stable readings.

Effortless Features. Simple 3 point buffer calibration in pH mode with automatic buffer recognition (Model CR-10) Toggle between pH and mV (Model CR-10). Toggle between compensated/uncompensated conductivity, salinity or total dissolved solid (TDS) (Model CR-30).

Colorado Portable Additonal Features. Meters are ergonomically designed to fit comfortably in either hand. Water resistant with IP-65 rating allowing the meter to be fully rinsed and protected in low pressure water environments. Perfect for field use, using battery saving icon.
