Add-on OmniCTRL system

Use this industrial grade 4-fold power strip for software-driven control and monitoring of equipment via LAN/Ethernet or Bluetooth.

Connect pumps, solenoid valves, or stirrers to one of four independent electrical sockets switching at zero current (ZCS), e.g., for automated respirometry, water quality regulation, shuttle box experiments etc.

Electrical parameters like input voltage and power consumption (in Amps) for each relay, can be monitored and logged in Loligo^® software for diagnostics of connected appliances.

Features

• Absolute waterproof (IP 67)
• Innovative sealed silicone keypad with mechanical feedback
• High performance components of the latest generation
• First waterproof mini-USB interface
• Backlit graphic display
• Firmware 3310 update via internet download
• USB-interface allows external power supply (No charging!)
• 1 to 5-point-calibration for pH and 16 different buffer sets

The pH 3310 is an excellent instrument for laboratory use and for all classical applications of mobile field measurements. It is designed for the collection of extended data series. A generous memory for 5000 GLP-compliant data together with a time-controlled data logger with adjustable intervals makes it unique for long term monitoring in field applications.

A special sleep mode saves power when performing long term monitoring in order to extend the operating life of the batteries. And if it should happen in spite of this that power will break down: When supplying the instrument with a new battery it will pick up the data collection again. After sampling the data can be transferred over the unique waterproof mini-USB interface to a PC or Laptop.

Typical Application: Professional mobile measurements everywhere where a demand for documentation and data transfer exists. Excellent double functionality of handheld and Data logger with extended memory in one instrument for example at pumping tests (ground water) in the field or temporarily monitoring of surface water etc.

The instrument comes in a protective hardcase including:

• 50 mL technical buffer (pH 4.01)
• 50 mL technical buffer (pH 7.00)
• 50 mL electrolyte solution (3 mol/L KCl)
• Filling beaker
• Holder
• 4 x AA batteries
• USB cable
• Quick guide

Features

• The new optimized membrane glass guarantees quick measurement even at low temperatures
• The silver ion-free reference electrolyte prevents interference by precipitated silver (self-cleaning)
• SenTix^® PLUS electrodes with Gel electrolyte and a plastic body are robust and shockproof.
• The membrane glass is optimally safe-guarded by a protective shield.
• SenTix^® H and HW electrodes: electrolyte flow speed can be adjusted for optimal use.
• The easy to use fill-hole cover prevents electrolyte from leaking out during storage.
• SenTix^® PLUS electrodes with liquid electrolyte – the capillary effect of the platinum wire guarantees constant outflow and prevents contamination by precipitates or dirt even during changes in temperature; with new membrane glass for an even quicker response.
• The SenTix^® HWD also measures temperature and it comes with a fixed 1 m cable.

SenTix^® HWD – proven and tested sea water pH electrode system with build-in temperature probe from German WTW is easier to use and offers more quality and precision.

This opto-coupler device USB2.0 ports, isolates your data acquisition device from power surges or transients. Plug your USB device into the isolator and then plug the isolator into a HUB or PC. The PC and your USB device now have no electrical connection but can still talk to each other. The module also transfers power from the PC to your USB device with no electrical connection. Your USB device is now protected and can be attached to other ground potentials without any ground loops that could destroy your computer, USB device and other attached electronic devices.

FEATURES

• Regulate oxygen or CO₂/pH levels in water
• Solenoid valve for gas flow
• Ceramic air stone for effective gas exchange

This accessory set is used for regulation of dissolved gasses (oxygen, nitrogen, and CO₂) levels in water. The solenoid valve can handle up to 8 bar and can be switched on/off using our PowerX4 Bluetooth/ethernet power strip. When activated, the solenoid valve opens and gas from a pressure bottle will flow through the tubing and out of the air stone as fine bubbles.
