Meinl Bongo Cajon Box Drum - NOT MADE IN CHINA - Super Natural Finish Playing Surface and Hardwood Body, 2-YEAR WARRANTY (BCA1SNT-M)

...reate cajon and bongo grooves — the wood playing surface has two zones for high and low pitch notes to give you the effect of playing traditional bongo drums with the added warmth and depth of a hollow wood cajon.
Perfect for acoustic shows and jam sessions — the bongo cajon is the perfect grab-and-go percussion instrument for singer/songwriter circles, spontaneous jam sessions, accompanying guitarists and supporting acoustic bands in coffee house settings.
No tuning required — an internal wood divider located under the playing surface separates the high and low pitch sounds from each other, and this will never go out of tune so you don't have to worry about the pitch going flat.
Hardwood, super natural matte — we use hardwood from managed forests to construct this bongo cajon for its naturally musical sound properties like definition, warm tone and projection (the same hardwood is used in some of our standard cajons and bongos).
Fits comfortably in your lap — measuring 15 ¾" L x 7 ¼" W x 6 ¾" H, the Meinl Bongo Cajon is designed to fit comfortably in your lap with the playing surface close to you (many players rest the bongo cajon on their legs while they play).
Hollow underside — turning the instrument over, you'll notice the underside is....

RCYAGO Dissolved Oxygen Meter with Electrode Filling Fluid

Dissolved oxygen meter is a precision instrument for measuring dissolved oxygen and temperature. The dissolved oxygen probe is a thin film with a polarographic sensor and a thermistor for temperature measurement and temperature compensation. The permeable membrane separates the measured solution from the sensing electrode but allows oxygen to pass through the membrane to react, and the concentration can be measured..
Dissolved oxygen refers to the concentration of molecular oxygen dissolved in water, generally expressed in mg/L (ppm) and saturation percentage (%), which is the percentage of dissolved oxygen in 1L of water. The oxygen concentration of our dissolved oxygen meter is 0.0-40.0mg/L, most of the range of dissolved oxygen meters on the market is 0.0-20mg/L. When measuring and calibrating, needn't open the protective cover of the electrode, just put the electrode in the solution for measurement..
Detachable probe, easy to replace, equipped with 6 probe protective covers and anaerobic water calibration powder. The film inside the protective cover cannot be taken apart. After using it for a period of time, the test value is inaccurate and the calibration is still inaccurate, and the membrane sleeve needs to be replaced..
