Tunze Aquarium Controllers & Monitors for pH, CO2, mV (ORP), and Temperature

Tunze CO2 Controller-SetTunze CO2 Controller-Set
The Tunze CO2 Controller-Set consists of pH Controller 7070, CO2 valve kit 7074.11 incl. power supply unit 5012.01. On account of the adjustable time interval metering system, a careful CO2 distribution is possible preventing an overdose. The pH Controller 7070 is a handy pocket-sized measuring instrument with wall holding device has a 13 mm, 3½-digit digital display, and is supplied complete with a long-life brand electrode made of glass, buffer solution, and 9 V battery. By connecting a CO2 valve, the pH controller can be extended to a complete CO2 control station.

Manufacturer Warranty: 2 years from date of purchase.Tunze pH Buffer

Tunze pH buffer
Tunze pH 5, 7 and 9 buffer solutions for calibrating pH Controllers.

Tunze mV (ORP) Controller-Set
Tunze mV (ORP) Controller-SetThe Tunze mV (ORP) Controller-Set consists of mV controller 7071 and switched socket outlet 7075.11 incl. power supply unit.
On account of the adjustable time interval metering system, a careful ozone distribution is possible preventing an overdose. The mV controller 7071 is a pocket-sized measuring instrument with wall holding device has the same construction as the pH controller. The unit is supplied complete with a long-life high-quality electrode of glass and 9 V battery. By means of a connected switched socket-outlet the mV controller can be extended to a complete ozone control station.

Manufacturer Warranty: 2 years from date of purchase.

Tunze Temperature Controller-SetTunze Temperature Controller-Set
The Tunze Temperature Controller-Set consists of temperature controller 7027/2 and switched socket-outlet 7028.10. The unit regulates the adjustable temperature with an accuracy of 0.1°C. In case of power failure, the battery buffers the display and switching data for up to two years. The micro-processor controlled temperature measuring and regulating unit 7027/2 displays the temperature on a large digital display with an accuracy of a tenth of a degree. The robust temperature probe is completely embedded in polyurethane resin, and hence is corrosion-proof and suitable for permanent measurement.

Manufacturer Warranty: 2 years from date of purchase.

Tunze Conductivity MeterTunze Conductivity Meter
A robust hard coal electrode and a temperature probe have been combined to a single-stick measuring electrode in these measuring instruments. These reliable pocket-measuring instruments come with a wall holding device and are automatically temperature-compensated. They can be employed as a field measuring instrument or as a stationary measuring station (power supply, accessory).
The units can be recalibrated by means of a calibrating solution.
Model 7032M is used to precisely determine the conductivity in fresh and salt water (up to 200 mS / cm).
