Digital Signal Output

The SQ-522-SS sensor outputs a digital signal using Modbus RTU protocol over RS-232 or RS-485. The sensor incorporates a rugged, self-cleaning sensor housing design, anodized aluminum body with acrylic diffuser, and high-quality cable terminating in pre-tinned pigtail leads for easy connection to dataloggers and controllers.

Typical applications include PPFD measurement over plant canopies in outdoor environments, greenhouses, and growth chambers, and reflected or under-canopy (transmitted) PPFD measurements in the same environments. Quantum sensors are also used to measure PAR/PPFD in aquatic environments, including salt water aquariums where corals are grown.

Full-spectrum Quantum Sensor

Measure photosynthetically active radiation, PAR, in µmol m-2 s-1.

Apogee Instruments‘ quantum sensors provide accurate and cost-effective measurement of photosynthetically active radiation (PAR) from all light sources used to grow plants and corals.

Spectral Response

The full-spectrum quantum sensor has a spectral range of 389 to 692 ± 5 nm. The improved spectral response increases the accuracy of LED measurements.

Accurate, Stable Measurements

Sensors are cosine-corrected to maintain their accuracy when radiation comes from low zenith angles. The sensors measure PPFD with a cosine response accurate within ± 5 % at 75° zenith angle. Long-term non-stability determined from multiple replicate quantum sensors in accelerated aging test and field conditions is less than 2 % per year.

Typical Applications

PPFD measurements over plant canopies in outdoor environments, greenhouses, and growth chambers, and reflected or under canopy (transmitted) PPFD measurements in the same environments. Quantum sensors are also used to measure PPFD in aquatic environments, including salt water aquariums where corals are grown.

Rugged, Self-cleaning Housing

Patented domed shaped sensor head (diffuser and body) facilitate runoff of dew and rain to keep the sensor clean and minimize errors caused by dust blocking the radiation path. Sensors are housed in a rugged anodized aluminum body and electronics are fully potted.

Ideal for Measurements in Air and Underwater

Apogee quantum sensor are calibrated to make absolute PPFD measurements in air. The waterproof sensors can be used to make absolute PPFD measurements underwater by applying an immersion effect correction factor, the SQ-420, SQ-520, MQ-210, and MQ-510 already apply the correction factor. For details on making underwater measurements, please refer to Underwater PAR Measurements.

Calibration

To ensure accuracy each sensor is carefully calibrated in controlled conditions and traceable to NIST reference standards. The full-spectrum sensors are pre-calibrated for all light sources.

Mounting

The AL-120 Solar Mounting Bracket with Leveling Plate facilitates mounting the sensor to a mast or pipe. The AL-100 Solar Sensor Leveling Plate is designed to level the sensor while sitting an a flat surface or mounting to a surface.

High Quality Cable

5 m of two conductor, shielded, twisted-pair wire; TPR jacket; pigtail lead wires; stainless steel (316), M8 connector.

Price excl. VAT., Excl. Shipping


KH Manager Test Reagent Concentrate 110451

The KH Manager Test Reagent Concentrate is specially adapted to the technical requirements of the D-D KH Manager
and enables the user to access exact measuring results of the KH Manager.

Mixing the test reagent
10ml concentrate is mixed with exactly 990g pure water.
For this purpose, the scale included in the scope of delivery of the KH Manager can be used.
The solution is then mixed carefully

Consumption
The KH Manager consumes approx. 15-16ml of the mixed test reagent solution per measuring run.
With 24 measurements per day, the daily consumption amounts to approx. 360-384ml.

Yield
Approx. 50l of test reagent solution can be prepared with the KH Manager test reagent concentrate.
One bottle of KH Manager Test Reagent Concentrate is sufficient for approx. 3500 tests. 

Costs
The average cost per test is approx. 0,01€.

Available in the following sizes:
500ml

D-D KH Manager - E1 Interface Box

Product no.: 6337

D-D KH Manager - E1 Interface Box 111200

 

With the D-D KH Manager E1 Interface Box, up to two D-D P4/P4 PRO dosing pumps can be connected to the D-D KH Manager or a single Kamoer FX-STP peristaltic pump. To connect P4/P4 PRO pumps, additional data connection cables are required, which are available separately.

 

Only cloud versions of the D-D P4 pump(s) that use the Kamoer Remote App can be connected to the D-D KH Manager. Both the D-D KH Manager and the D-D P4/P4Pro dosing pump(s) must be connected to the same cloud account via a router in order to use the control function.

 

The connection to the D-D P4 and P4 PRO pumps allows automatic adjustments to the programmed schedule of one or more dosing pump heads after each KH test, eliminating problems with over- or under-dosing that often occur with traditional dosing methods. If you control a single KH buffer dosing head, your programmed additions will automatically increase or decrease depending on the test result and the parameters you have set in the D-D KH Manager to maintain a stable KH value. All dosing heads on the D-D P4/P4 PRO pumps that are not intended to be automatically adjusted can be set to run an independent dosing schedule as usual without the KH Manager making any adjustments.

 

With this control, multi-part dosing systems can also be adjusted by the KH manager or the dosage of other elements such as calcium and magnesium can be increased or reduced according to the KH consumption of your aquarium.

 

 

 

When you connect a Kamoer FX-STP, the connection allows the KH Manager to turn the FX-STP on or off for a specific time depending on the test results. The dosing speed can still be controlled via the FX-STP.

 

When used with the FX-STP nothing further is required for the connection, when used for the P4/P4PRO a data cable is required from the E1 to the pump, when used with 2 x P4/P4 Pro two data cables are required.
