Zebra-Tech D-Opto Dissolved Oxygen sensor and logger

The Zebra-Tech D-Opto is an optical dissolved oxygen instrument. This is ideal for long term monitoring of dissolved oxygen in marine environments, as well as lakes, rivers and streams. In situations where there is a lot of bio-fouling,  the D-Opto Shutter system is available to cover the sensor window and keep it clean when not actually making a measurement. This is controlled by the same data logger as is connected to the D-Opto sensor. The D-Opto range consists of: D-Opto Sensor D-Opto Logger D-Opto Shutter To download the D-Opto data sheets click here ...

Zebra-Tech Wet Tag – Data collection for fisheries

Fisheries catch sampling with the Zebra-Tech Wet Tag Turn your lobster pot, crab pot or dredge into a data collection tool: Turn your fishing gear into a data collection tool. The new Wet Tag from Zebra-Tech is a small low cost logger designed to be fitted to fishing and research equipment to record data and transmit it to the Deck Logger without requiring data entry or effort by the user. It works in combination with the Deck Logger to streamline the process of gathering catch data. Developed in cooperation with CRAMAC 5 of the New Zealand Lobster industry. Temperature (average and max to 0.25 Deg C) Pressure (Average and max) Soak time Tamper event (was the pot lifted while I was away?!) Pot / Dredge ID Boat / fisher ID Path and position data can be added – When used with Deck Logger Download the Wet Tag data sheet here  ...

Zebra-Tech Dive Caliper

The Zebra-Tech Dive Caliper is every divers measuring tool With the Zebra-Tech Dive Caliper you can record measurements at the press of a button and eliminate transcription errors while at the same time speeding up your work. With an operating depth rating of 40 metres, the Dive Caliper is used by scientific divers, fishing divers and engineers during benthic surveys, maintenance programs, oil and gas engineering measurements. When ordering two Dive Calipers for his post-graduate students, a university professor who has been studying coral reefs for 30 years stated that he wished the Dive Caliper had been available when he was studying for his PhD. At the end of diving, simply connect the Dive Caliper to a PC and download the CSV file into a spreadsheet. Download the Zebra-Tech Dive Caliper data sheet here      ...

Zebra-Tech Hydro-Wiper

Zebra-Tech Hydro-Wiper The Hydro-Wiper is an innovative mechanical wiper system designed to keep the windows of optical sensors clean. It is  designed to fit easily to a wide variety of instruments, and is also used very successfully for underwater cameras. Using a regular gentle brushing action, the Hydro-Wiper keeps the optical window of the instrument clear of bio-fouling and unwanted mud deposits. This reduces the need for expensive site visits to clean the instrument  by hand, and helps to maintain data integrity throughout long deployments. Zebra-Tech has created a range of models that are now being used by educational institutions, government agencies and private companies in all parts of the world. We probably have a model for your instrument. If not, we will build you one. Download the Zebra-Tech Hydro-Wiper data sheet here...

McLane ITP – Ice Tethered Profiler

McLane ITP - Ice Tethered Profiler The McLane ITP is a moored profiler which has been designed to be deployed through a small hole under the ice. It collects measurements of conductivity, temperature, and depth, and other sensors. Data is recorded on board, and can be transmitted automatically in near real time using an inductive modem connected to a surface controller. Deployment parameters including profiling depth, time intervals and pressure stops are pre-programmed by the user, and profiling patterns can span specific seasons or timeframes.

McLane Steel flotation

McLane Steel flotation for buoyancy down to 380m McLane steel subsurface flotation is a cost effective solution for shallow water and coastal buoyancy requirements down to 380 metres. With a heavy steel construction and durable finish, our highly efficient buoys withstand the harsh ocean environment and strenuous deployment procedures. McLane Steel subsurface flotation feature an equatorial ring for strength, a strong straight-through central strain member, lifting beckets and sacrificial anodes. Steel flotation buoys come in three diameters: 30” (369 lb, 168kg buoyancy), 37” (700 lb, 318kg buoyancy) 41” (898 lb, 407kg buoyancy). Download the McLane Steel flotation data sheet here...

McLane Glass flotation

McLane Glass flotation is based on 12" spheres McLane Glass flotation is ideal for deep ocean moorings and instruments. All McLane Glass flotation modules are based on 12" borosilicate glass spheres protected by polyethylene hardhats, and depth-rated to 7,000m. The multi-sphere hardhats have a central tension rod for installation in a mooring line. This eliminates mooring cable twist for better performance. G2200 single sphere model (10kg buoyancy), G6600 triple sphere model (30kg buoyancy) G8800 quad sphere model (40kg buoyancy). Download McLane Glass flotation data sheets here  ...

McLane MMP Moored Profiler

McLane MMP Moored Profiler climbs up and down a wire The McLane Moored Profiler (MMP) travels up and down a fixed mooring wire, carrying a selection of oceanographic sensors. Standard instruments include a CTD and an acoustic current meter. Additional sensors often include a variety of bio-optical, chemical, and suspended particle sensors. The profiling depth and interval and optional pressure stops are all programmable by the user, and acquired data is recorded on board. Optional inductive modems can be used to provide  near real-time telemetry of the acquired data up to a surface buoy or down to a seabed node and onwards to the users office.

McLane WTS-LV Large Volume Sampler

McLane Large Volume Samplers can pump 36,000 litres of sea water The McLane Large Volume Water Transfer System (WTS-LV) is used to collect a single sample onto a 142mm membrane filter by drawing ambient water through the filter holder without passing through the pump first. It is most commonly deployed suspended from the hydrowire of a research vessel. Depending on the filter installed it may be used to collect suspended particles, particulate trace metals, phytoplankton or micro-plastics. The WTS-LV is available with a choice of pump size to suit a range of filter porosity depending on the specimen to be collected. As material accumulates on the filter, the pump speed dynamic algorithm adjusts  to minimise the risk of a damaged sample and maximise battery endurance. The filter holder is modular and designed to evenly distribute collected material. A three-tiered filter holder option is also available. There are  four configurations of WTS-LV : WTS-LV-Standard     - 10Ahr battery pack (up to 15,000 litres of seawater) WTS-LV-Upright       - High...
