PreSens’ wide range of accessories makes it possible to expand the usability of our fiber optic pH measurement devices. Our integration system supports sensor handling, and sensor adapters allow our pH sensor spots to be used in a wide variety of containers.

PreSens offers a variety of accessories for pH meters. Below we have selected a few to describe, but if you are looking for something specific that is not listed, feel free to contact one of our sales representatives for more information.

MANUAL MICROMANIPULATOR MM

The Manual Micromanipulator MM is specifically designed for PreSens needle-type microsensors (NTH). The system enables vibration-free movement of the microsensor in 3 axes with micrometer reading accuracy. A solid base plate ensures a stable setup of the micromanipulator and allows the entire system to be safely tilted up to 90°—enabling use in any position. With the secure insertion function, the microsensor retracted in its steel needle can be safely inserted into the target area. The sensor tip can then be gently and precisely extended without risking damage to the sensor fiber.

CLAMPS UNIVERSAL SFS

These clamps are used with the SFR Shake Flask Reader and SFR vario. They ensure that the sensors integrated into SFS sensor flasks are properly aligned with the reader optics. There are two additional holes in the base plate to accommodate the knobs on the plastic bottom of the SFS flasks, securing them in place. The clamp also features a recess for biomass optics in the SFR vario and a side arm to hold glass flasks with integrated sensors in the correct position above the optics.

HEAVY STAND (HS)

The Heavy Stand (HS) ensures safe mounting and operation of the automated micromanipulator. The heavy base plate allows for the most stable and vibration-free setup. HS includes two square profile rails of different lengths so that the micromanipulator can be installed at different heights and adapted to various samples. Additionally, two metal rods can be attached to the HS for mounting additional measurement equipment such as VisiSens, cameras, or lighting next to the AM. HS can be leveled using its three adjustable feet and the spirit level integrated into the base plate.

SMA-ST ADAPTER

This adapter is an accessory for SensorPlugs. Since SensorPlugs work with a 1 mm polymer optical fiber with an ST connector, the adapter is required to connect the fiber to the SMA port of the corresponding meter (e.g., pH-1 SMA HP5 or CO₂-1 SMA).
The SMA-ST adapter is tested for SensorPlugs. It is not suitable for connecting other sensors with ST fiber connectors (such as microsensors) to an optical meter with an SMA port.
