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.

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.

need a smooth sink surface for this to work
Color: Silver
Suction cups didn't stick to my sink and kept falling; to be fair, surface of my sink is textured.

Three months later, it's a keeper
Color: Silver
I hate it when reviews are left one day after the product arrives. At that point, there's no way of knowing if the item is going to last. When my last sink caddy went bad (the suction cups rotted out and the wires had started to rust), I ordered this as a replacement. Inexpensive, functional, worth a try.
There were two things that impressed me when this arrived. The suction cups weren't permanently mounted, so if they fell apart, the caddy was still worthwhile. Secondly, the company offered free replacement suction cups if the time came I needed them. That struck me as above-and-beyond; I had no idea this was part of the package.
I'm happy with this. It looks good, I detach the sink caddy regularly when I want to move it out of the way, and it pops right back into place. For the money, I don't think you can beat it.

Great caddy. Well built.
Color: Black, Color: Black
This is a great caddy for my sink items. Holds the dishwashing liquid, hand soap, sponge, brush and still has room for more. The only suggestion is to allow the brush cage to also be above the drip pan so you have more space. I know I can add the brush cage into the main compartment to drain it but I prefer the extra space. This is very sturdy and is the perfect width and height for many sinks.

Well made, well thought out!
Color: Black
I like that the caddy has a bottom and that the drain is movable. The adjustable separator is also a plus and I can move the tall attachment inside so that I can keep my wet brush there and it will drain into the sink.

Good organizer!
Color: Black, Color: Black
This is perfect for keeping all my sponges and brushes all in one place! I love when things feel more organized. I also really like how the excess water drains out of the bottom back into the sink!
