DDB-11A nau'in mai ɗaukar hannu conductivity mita, shi ne 3 1/2 bit LCD dijital nuni conductivity mita, shi dace da dakin gwaje-gwaje da kuma samar da filin ma'auni, mafita conductivity, saboda kananan kayan aiki girman, ɗaukar da sauki, musamman dace da wuraren da babu AC ikon samar da mafita conductivity ma'auni.
II. Main fasaha aiki
1, auna kewayon: wutar lantarki conductivity 0 ~ 10⁵μs/cm， An raba daidai da juriya ∞-10Ω · cm zuwa 3
Basic sikelin da biyu ƙarin sikelin, duba tebur
2, daidaito: ba fiye da ± 1% (cikakkiyar) ± 1 kalma
3, kayan aiki siffar girma: 160 × 90 × 40 (mm)
4, kayan aiki yanayi:
① yanayin zafin jiki: 5 ~ 40 ℃
② dangi zafi: ≤85%
② Wutar lantarki: 9V (6F22) baturi
