Pinpoint Nitrate Monitor

[hnugraha]

Baru browse Nitrate Monitor-nya Pinpoint. So far gak nemu negative review di internet. Ada yang tau kalau utk Nitrate, alat ini reliable gak?

Kalau Pinpoint Calcium-nya banyak yang kasih negative review soalnya... pH-nya sih OK banyak yang pakai dan bagus.

saya jg lage nabung buat nitrate monitor.. masih mahal seh harganya.. itung2 sekitar 2.6 juta.. sejauh yg saya tau termasuk OK qualitynya minusnya cuman harganya itu yg mahal..

PH monitor saya ada pakai, lumayan menghemat waktu ukur2 PH.. :wink:

yo wis Har, elo beli aja dulu Nitrate Monitornya. Terus elo review disini. Kalo bagus baru gw mau ikutan beli ...

Wakakaka. Tumbal kelinci percobaan. Ntar ah, tunggu feedback Forum seberang kalo gitu.

Tester elektronik prinsipnya kan ngukur tegangan atau arus. Menurut gw sih kalo nitrate dibawah 25 part per miliion pasti gak akan bisa diukur secara presisi.

Paling2 akurasinya +/- 25 ppm ... hehehehe
Coba cari specs nya Har, barangkali disebutkan akurasinya.

Gw punya PinPoint Salinity Monitor, kagak akurat sama sekali. Refraktometer ngukur 35 ppt, kalo pakai Salinity Monitor malah kebaca cuma 28 ppt ... jauh banget.

BTW aqua elo Nitrate nya berkisar di berapa ppm ?
Punya gw gak pernah bisa 0, selalu ada di 5 - 10 ppm.

Salifert terukur 25ppm. Tapi gw gak yakin, karena SPS happy2 aja, warna jg gak berubah. Mangkanya gw pernah ngusulin bikin workshop water parameter testing dong. Gak pede caranya nih.

Btw, Juuniz sama Adrianto, gokil ye page2 udah online. Bukan baru pulang ronda pan? Hehehe...

Nih dari websitenya, ada 2 range:

Pinpoint Nitrate Monitor has 2 independent ranges:
0-10 ppm NO3
10-100 ppm NO3
Accuracy for either scale after calibration is ± 1 ppm. Resolution for either scale is 1 ppm NO3.

loh saya postingnya malam hahaha sewaktu cek perkembangan saham xD

 

[hnugraha]

??!?? oh iya. hahahaha. berarti gue yang kepagian. hahahaha

Ok, ini dari Randy Holmes-Farley sendiri, yang expert-nya Reef Central. Masih anget thread awal tahun ini. Seems OK ya ini alat.

I have one. I cannot comment on the accuracy as I have not tested it in that way. It is not suitable for leaving in the tank 24/7. What you do is calibrate it like a pH meter in 2 solutions (1 and 10 ppm or 10 and 100 ppm, depending on the range you need), and then you put it into the solution that you need to measure. The whole process takes just a few minutes.

It gave fairly quick and reproducible vales for my tank water (about 10 ppm, which was surprisingly high, but I have not used a kit on it in quite a while). There is no problem telling what the determined value is.

Assuming it is accurate, it would likely be a good choice for someone that cannot read test kits well.

Also, assuming that the standards that come with it or can be purchased separately are made correctly, those standards could be used to test nitrate test kits, if one were so inclined.

Colorimeter yang paling akurat untuk test nitrate, phosphate, dll
Beli dong Boss ....

 

[hnugraha]

WHOA. harganya mangkin2 cak. Lagi eman2 jatah hobby bulanan nih (kesian tuh koi lama gak dicolek2 filternya). Balik Salifert dulu aja, sekalian ngabisin reagent-nya. Kebanyakan diukur2 lama2 senewen loh. :shock: reading nitrate gw teuteup 25ppm hari ini, tapi SPS nya gak jadi coklat, masih bagus2. Apa kadaluarsa ya test kit-nya?

Most important habit ganti air, rajin bersihin skimmer, tweak denitrator, sama RowaPhos. Ntar kali kalo ada biz trip travelling liat2 toko yang jualan alat-nya.

 

[Adrianto]

Kalo SPS masih warna cerah, no worries lah ...
Gak perlu terlalu sering di test.

Nitrate gw juga kagak pernah turun dari 5 - 10 ppm. Padahal udah pakai Refugium Caulerpa, Sulfur Denitrator dan Vodka Denitrator.

Ikan banyak udah pada gedhe banget, makan banyak, kotoran banyak pula. Skimmate tiap hari bisa 500ml kental dan bau.

Yo wis ... kalo seandainya berubah pikiran dan mau beli Colorimeter ... gw nunut test air ya.

menurut sy tdk perlu bgt deh gadget seperti itu, toh kalo system setnya bener parameter air juga di anjurkan cek 1 bulan 1x. yg bikin panik kalo probe ngaco... tapi kalo ada dana nganggur boleh juga yah buat di liat liat
