Adakah mbah suhu yg sudah pake tambahan digital torque wrench dgn harga sekitar 600-650k?
yang kaya gini :
mxita-digital-torque-adapter-wrench-1-or-2-2-200nm-ban-mobil-2-200n-black-3.jpg
hampir saja beli model kaya gini saat lagi putus asa dan belum dapet wahyu dari mbah shifu....
Wah ini ane udah pake dari awal tahun, merknya sama MXITA juga beli di Lazada waktu itu harga 538 ribu udah sama ongkir.
Sekalian ane review aja yaa di sini:
Pas mau beli ada 4 pilihan tipe dengan range Nm yang berbeda 0.3-30Nm, 2-200Nm, 10-200Nm, dan 17-340Nm. Ane beli yang 2-200Nm karena yang butuh baut yang butuh torsi di atas 200Nm cuma baut driveshaft depan aja (270 Nm) di mobil ane sedangkan yang butuh <17 Nm lumayan banyak.
Waktu itu juga agak ragu gimana akurasinya, nemu
artikel yang udah review torque adapter model ini ternyata akurat juga, bahkan bisa lebih reliable daripada torque wrench konvensional karena kalau torque wrench konvensional pas nyimpen ga diset ke torsi terendahnya bakal berkurang akurasinya lama-lama.

We originally gathered a small collection of standard 12-inch drive clicker torque wrenches including a Snap-on, a Craftsman, and a Harbor Freight. Then we discovered a digital torque adapter sold by Harbor Freight. This small unit fits in between a standard 12-inch drive breaker bar and the socket, and using a digital strain gauge, it converts the torque applied through the adapter into a digital readout. At a typical Harbor Freight price of $39.99, we decided to include it in our test. We frankly didn't expect this little unit to be very accurate. But testing proved otherwise.
We ran the torque adapter through five consecutive applications of 70 lb-ft of torque to watch it hit within 0.10 of a lb-ft twice and actually hit exactly 70 lb-ft on one occasion. The average of the five tests was an amazing 70.1 lb-ft. The unit offers a digital readout and warning lights, and it even emits a progressive electronic beep when nearing the pre-selected torque.
Next, Chauvie suggested an even more interesting test. He offered to keep our Harbor Freight 12-inch clicker wrench and test it every 30 days for two months while keeping the wrench loaded at 70 lb-ft. He said the problem with clicker torque wrenches is, when the mechanic fails to return the preload to its lowest setting after each use, the tool begins to lose accuracy. Chauvie says the longer the wrench is loaded, the less accurate it will become. He has since reported on the torque wrench's performance at 30 days and 60 days, and we've included a graph to show the results (page 30). This inaccuracy occurs because the internal spring loses its tension, allowing the wrench to break away (click) at a lower torque value. Chauvie says this is a common problem for all types of clicker torque wrenches. The point here is that you should always return your clicker torque wrench to the base setting before storing the wrench. This simple step will maintain the wrench's accuracy for years instead of mere months.
Walau merknya yang ditest di artikel beda, PITTSBURGH Pro dari Harbor Freight vs yang dari Lazada merknya MXITA, model serta kelengkapannya sama persis, kemungkinan sih 1 pabrikan.
Dapet carrying casenya juga yang include converter 1/2" ke 3/8" dan 1/2" ke 1/4"

Dapet sertifikat kalibrasi juga yang nampilin % deviasinya pas ditest di pabrik

Sejauh ini udah dipake buat ganti engine mounting, shock, bongkar pasang jok (pas bersihin interior), ganti kampas rem depan belakang, ganti arm, ganti belt masih aman. Minusnya katanya kalau ditaro di casenya suka kepencet tombol powernya jadi batrenya cepet abis, jadi tiap abis pake ane lepas aja batrenya biar ga abis.

Sekian review singkatnya dari nubi, dengan harga 500ribuan dapet torque wrench yang rangenya lumayan lebar jadi lumayan kere hore sih menurut ane
Tapi mungkin kurang cocok buat suhu-suhu di sini yang prefer torque wrench dengan harga juta jutaan hehe
