MICROPROCESSOR METERS for professional monitoring
This improved meters were specially adapted for use in aquaculture and
limnology. The compact (L x W x H 165 x 83 x 34 mm, approx. 305 g)
splash-proof cover (IP 54), the plastic sensor (14 mm Ø, 150 mm long, with
1.5 m cable), the very long sensor life (approx. 2 years standby time), and
the delivery with NiMH-batteries (2 x AA Mignon) and USB-cable with charger
in transport case, make these meters perfect for field work or laboratory
use. The large graphic multi-display makes the readings available clearly
and quickly. The short polarization time (approx. 30 sec. max. 5 min.), the
low flow current sensitivity (1 % at 5 cm/sec.), the high precision +/-1
digit (0.1 mg, 0.5 % or °C), as well as salinity correction, automatic
air-pressure and temperature compensation (in the range of 5-40 °C) makes
working easy. Automatic calibration with the calibration chamber (included)
is an additional feature. Options include stainless steel sensors
(4.7-5.4 mm), and other cable lengths available. To enable you assigning measured values
geographically, these meters are available with or without GPS.
The following models are available as standard:
OPTICAL DISSOLVED OXYGEN SENSOR to connect on systems or computers
This new development is the first optical oxygen sensor with SCS interface (Simulation Clark-Sensor), for a perfect integration into running systems. The ideal substitute for your existing oxygen sensors. Via the SCS interface downward compatible to classic oxygen sensors (galvanic isolation), works together with classic transmitters. Additionally, the sensor can be connected via the 4 to 20 mA current output or with a process control system (SPS). As acessoire, a PC-adapter (USB-RS485) is available, with which the sensor can be connected directly to a personal computer, and configures from there (Software for free), where just a net-device is needed and no external meter. The calibration is simple and only needed once as the calibration data can be stored in the sensor. The robust and simply exchangeable sensor cap has a warranty of 2 years. It guarantees stable values at once, little drift, quick reaction time, and all independent from incoming flow. The sensor has no no sensitivity towards H2S or CO2, but an automatic temperature compensation and malfunction diagnosis. Measrement range 0-20 mg/l, 0-200 % sat., resolution (at 25 °C) +/- 1 %, limit 0.1 %, reaction time < 60 s, temperature range -5 to +50 °C.

MULTICHANNEL PROCESSERS for control and management
This very versatile instrument can be used as a
stand-alone wirless and solar powered multi channel controller for cages, ponds, tanks and
raceways, etc. If there are more than one transmitter units and a base station receiver,
then the system automatically configures as a network and sends the information by low
powered wireless communication to the base station. The base station has 2 alarm outputs,
so it is easy to connected it to a telephone dialer or a local alarm. The base station
connects to a PC via a USB, so now you have all the information displayed on your PC and
all the results can be data logged. You can add up to 50 monitor units onto the one
base unit, to make a 100 channel network with no wires and no installation
costs. This makes for a really low cost simple system and for the first time provides
a package ideal for cages, ponds or for any installation that can not use wires. In the
event that you get hit with lightening, then generally only one unit will be affected, and
if it can not be repaired on-site then you simply send the faulty unit back and replace
with a working unit. This means that you are in control of your own system and not
dependent on service engineers.
MODULAR MULTIPARAMETER measurement and control system
When it comes to automatically controlling and adjusting critical water parameters, it leaves nothing to be desired. Due to its flexible modular concept, the system is the perfect solution for most applications in aquatic environments. Apart from comprehensive timing functions, it provides measuring modules for the parameters of pH value, redox potential, temperature, conductivity, level (fill level), oxygen and air pressure. Up to eight sensors can be linked to the system in any requested combination. This allows, for instance, simultaneous pH value-measurement and adjustment in eight different pools – which is so far unique. Connection facilities for up to eight measuring modules in any requested combination allows for connecting up to 16 switching outputs (4x4) for control and adjustment functions measured data storage for 2000 measuring chains battery backed computer interface for PC-data evaluation with the software, capable of being network-integrated by LAN adapter, flash memory technology for update-function, automatic sensor identification and sensor testing, day/night simulation, lunar phase simulation, high/low tide simulation, flow simulation, timer clock functions, time interval functions, night modus, acoustic, optical and external alarm, etc.
