Whilst maintaining a high level of quality and
efficiency these controllers are well priced in the marketplace.
Swimming Pool / Process System Controller
Dual pH and ORP
Controller
|
The Setup and calibrations are entered with easy to use encoders. Programmed parameters are not lost even if power is switched off for extended periods. Precision 4-20mA output with complete isolation between each unit enables the connection to a central monitor or data logging system. mA calibration and signal range are performed through software and kept in non-volatile memory. Various timing modes and dosing relay lock-out times protect the installation from excess dosing. |

Auto
Mate II Controller The Auto Mate II is a swimming pool controller. This controller combines
the two common process controls required for a swimming pool pH and ORP
control. It also includes a timer with 6 independent on/off cycles over 7
days for a filter pump. This controller is ideal for Domestic swimming pools, It has been designed over 2006 and 2007 to provide excellence to the pool industry. It provides the quality features needed with out the complexity of most controllers. Setup and calibrations are entered with easy to use encoders. Programmed parameters are not lost even if power is switched off
for extended periods. This instrument makes it easy to keep swimming pool chemistry balanced at all times. |

Conductivity and Temperature

CTH-2 Cooling Tower Controller The CTH-2 controller has all of the necessary
functions for cooling tower control built into a single easy to use
controller. It incorporates conductivity control with inhibitor dosing
functionality with many modes of operation. It operates over a 0-5000 uS range with automatic temperature compensation. The
conductivity is displayed on a back lit screen that provides easy to
understand programming advice and operational descriptions. The biocide functionality of this unit is the
most advanced seen in the Australian market. It comprises of two independent
timers, biocide one functions on a 7 day cycle. The secondary timer operates
on a 28 day cycle, essentially allowing the unit to slug dose chemical once
each month. The CTH-2 is state of the art - it is the most
effective, functional and economical unit available in |

Digital Timers
|
DTH-1 Timer The DTH-1 is an industrial quality timer unit.
It allows switching of a 240VAC relay on 6 independent on/off cycles over 7
days. This allows up to six switching cycles 7 days per week! The timer has an integral battery backup
meaning that if a power supply fails the time and program will be retained. |

Simulators
|
SMH-2 Simulator This hand held simulator is ideal for
commissioning, testing and troubleshooting pH and ORP based systems. The
simulator can be connected to the instrument and an output ranged to simulate
a process. The control and operation of the system can then be tested. The simulator also can be connected to the
sensor to obtain a reading independent of the controller. |

pH and
ORP Controllers
|
PMV-1 ORP Controller The PMV-1 is an ORP controller designed for
cooling tower or process application. It utilises a sensor to measure the
level of oxidant in the water, when a certain level of ORP is reached the
controller will trigger dosing cycles. The dosing cycle can operate in three ways. The first operates by cycling on / off timers,
this is known as normal. The second operates in a proportional manner,
dosing towards the set point at a reduced rate. This avoids over dosing. The third is known as adaptive proportional
capacity to 'learn' from the behaviour of the system and adjust it's on and
off by an algorithm programmed into the instrument. It also features an alarm and 4-20 mA output. |

PPH-1 Controller The PPH-1 is a pH controller designed for
cooling tower circuits. It utilises a sensor to measure the level of pH, when
a certain level of pH is reached the controller will trigger dosing cycles.
The dosing cycle can operate in three ways. The first operates by cycling on / off timers,
this is known as normal. The second operates in a proportional manner,
dosing towards the set point at a reduced rate. This avoids over dosing. The third is known as adaptive proportional
capacity to 'learn' from the behaviour of the system and adjust it's on and
off by an algorithm programmed into the instrument. It also features an alarm and 4-20 mA output. |
|
|
The This unit controls either pH or ORP and has
facility to correct 'up' or 'down'. A proportional output means that the
response of the attached equipment (such as metering pumps) can be paced to
accurately maintain the required set point without overshooting. |
