Ohaus AQUASEARCHER™ AB33M1 Standard Multi-Parameter Bench Meter
OHAUS AquaSearcher™ AB33M1 benchtop meter is designed to be reliable, efficient and user friendly. The i-Steward ensures repeatable and consistent measurement accuracy for optimal peace of mind. Large LCD display and touch keypad makes changing the parameters, executing setup, and performing calibration as simple as using a smartphone.
i-Steward Indicators include the electrode condition, “Electrode Dirty/Broken,” and reminder when meter needs recalibration. Perform up to a 5-point calibration using automatic buffer recognition of 5 predefined buffer groups. Calibration log stores ten most recent calibrations. Compact stirrer can be used to uniformly mix solutions to get fast and repeatable results at no additional cost.

Features:
• With multifunctional touch keypads, AB33 makes measurement simple and fast
within 3 steps. The intelligent i-Steward monitors the condition of electrodes,
ensuring accuracy of the results.
• Able to store up to 1000 items in its internal memory, AB33 allows for efficient
data documentation. Standard RS232 and USB interface allows
connection to external devices for expanded storage.

cell conductivity probe compatibility are all features well suited for universal
laboratory applications.
• Adjustable TDS Factor - The factor that relates conductivity to total dissolved solids is based on the type of sample being measured. To have correct temperature compensation when measuring conductivity, the linear compensation coefficient adjusts by automatic temperature compensation. Selectable reference temperatures of 20 or 25 ºC for temperature compensated conductivity readings.

Great quality, easy to set up.
Size: 3 Panels, Color: Grey, Size: 3 Panels, Color: Grey
I actually have this in my bedroom, replaced a non acoustic panel with it. These make a huge difference. As someone who is always playing music on their speakers I don't want to bother my roommates too much. Easily can hear the difference once these were in place. The panel itself is high quality and thick, what's a really nice detail is how they are attached together, there are multiple wedges just like foam noise dampeners which is super cool! This thing is easy to move around and can be folded for storage with ease. You get extra screws just in case you lose any, the feet are made out of metal which adds to the quality. There was a very slight chemical smell when taking it out the box, however that went away in just a few hours.
I can imagine using this in a noisy office, surrounding yourself with these in a cube shape will make all the difference to focus on your work. These panels are great and if you're looking for quality, I'd say you can pick these up without worry. No issues on my end!

Office Divider
Size: 5 Panels, Color: Grey
This office divider is well made and easy to assemble. All you have to do is install the feet. The panels are only about an inch thick, but they work surprisingly well at muffling unwanted background noise.

Easily Create a Workspace
Size: 5 Panels, Color: Grey
Such a great design. I am loving the versatility of these - very easy to set up and also to store. THe color is perfect for them to blend into the decor. While they don't cancel out the noise altogether, they reduce it and decrease distractions. No installation needed - has its own supports. Built really well with good materials - sleek and sturdy and solid. They have increased the privacy and have helped make a great space without difficult construction. Work well and they are great value for money - instant privacy and space.

Perfect for my company's temporary needs
Color: Gray, Size: 72" wide, 66" Tall
My company ordered multiples of these dividers to separate desks in much smaller temporary space we had to use after our offices were flooded in August 2023. (Yeah, I know - just getting around to reviewing them now!) These fit the bill perfectly. Granted a bit of privacy so we weren't staring at the employee next to us. Easy to put together; excellent value.
