The Edge pH meter from Hanna Instruments is a new highly refined digital testing device which firmly breaks away from the design standards of contemporary laboratory testing equipment. Rather than looking like a blocky and intimidating slab of water testing plastic, the Hanna Edge looks like it was made from the mold of a modern smartphone with a huge LCD screen, touch sensitive buttons and a thin profile that makes it almost pocketable.
Despite having a 5.5 inch high contrast monochrome screen and a really avant-garde appearance, what makes the Edge pH meter so tantalizing is its ability to also accept a conductivity probe or a dissolved oxygen probe. The edge doesn’t use the laboratory standard BNC connection for its probes and opts instead to communicate via a mall 3.5mm audio-style jack; this in part to make the Edge as ungainly as possible but also, probably, to lock customers into using Hanna’s probes with the proprietary connection.
The Hanna Edge is quite possibly the antithesis to theHanna Checkerwhich was geared towards the aquarium hobby with a $50 price point. Meanwhile the half inch thick Hanna Edge is firmly targeting the critical testing applications of water testing labs which will be attracted by either its portable nature, its wall mount for monitoring application or the benchtop cradle and probe holder for cycling through lots and lots of samples.
基本pH测试包的价格为400美元，汉娜（Hanna）边缘附带壁挂式持有者，摇篮和探头架，带有温度传感器的玻璃体可再填充pH探针以及校准解决方案，电缆和充电器，以获取这种新的高性能水测试工具包装的工具处理。其他可用于边缘的电极包括高级电导率和溶解的氧气传感器，均价格为每张335美元。
使边缘的电极独一无二的是在板上芯片，该芯片由校准的缓冲区，日期，时间，偏移和斜率特性预校准。我们不太确定这一切的含义，但我们收集的意味着这些电极比我们通常在水族馆中使用的可更换凝胶填充探针更复杂。我们不认为边缘会吸引休闲水族馆，但是LFS，公共水族馆和鱼类苗圃正在处理大量水样边缘to using the Hanna Edge pH meter over conventional testing methods. [Hanna]
