At first glance and touch, they're not exactly cheap meters. The package does not contain calibration solutions, PH 4,01, PH 7,00 ( possibly 6.86, ) and PH 10 ( or 9.18 ) are required. I don't mind, I've got all my own. And also calibration to 1413 conductivity. Could be a backlit display and a Hold feature. For the money, I'm sure. Yeah, and the scope of connectivity could be over 2,000. The greatest advantage is calibration using a screwdriver. That's why I bought this machine. I'm quite satisfied.

Na první pohled a dotek to nejsou ty úplně levné měřáky. Balení neobsahuje kalibrační roztoky, potřeba jsou PH 4,01, PH 7,00 ( případně 6.86, ) a PH 10 ( nebo 9,18 ). Mě to nevadí, mám vše svoje . A taky kalibrace na konduktivitu 1413. Mohl by být podsvětlený displej a funkce Hold. Za ty peníze určitě. Jo a rozsah konduktivity by mohl být víc než 2000. Největší přednost je kalibrace s použitím šroubováku. Kvůli tomu jsem kupoval tento přístroj. Jsem v celku spokojen.
